Its human nature to want a quick fix in resolving issues or problems. Getting maximum results with minimal effort certainly has its appeal. From Thigh Masters and Bowflexes to The Clapper and Ginsu knives, the promise for rapid results and convenience can draw consumers in like the late-night glow of the TV infomercials selling these items.

But, lets be honest, these examples may have yield their desired results, but most products end up being a total disappointment and waste of money. This is also the case with certain medical procedures or therapies claiming to fix certain ailments or chronic conditions. As a patient-consumer, its important to do your research and not let emotions or false hopes guide you into making a potentially expensive or even risky decision involving your health.

One item in general, stem cell therapy, has been getting quite a bit of attention of late. Many may ask, what are stem cells? Stem cells are cells that have the potential to develop into many different types of cells. Think of them as a blank canvas which can divide and become specialized cells within the body such as blood, liver, or muscle cells. Stem cell therapy acts by introducing these cells into some areas of the body, to which the stem cells can divide regularly to regenerate and/or repair existing tissue. Stem cell therapy has long been used by physicians to treat certain types of cancers, such as leukemia and lymphoma as well as treating some bone, skin, and corneal eye injuries. But, while stem cells continue to be studied as potential treatments for other ailments and conditions, there are very few of these treatments currently that have been proven to be effectivelet alone safe.

With catchy, even gimmicky, tag lines like make me walk again, feel young again, or no surgery, no side effects, clinics (both in the United States and outside of it) are offering stem cell therapy to treat a laundry list of conditions. The problem with it is patient testimonials and gimmicky marketing techniques can be misleading. One resource beneficial in better understanding stem cell therapies is the International Society for Stem Cell Research (ISSCR). It represents academia and industry on a broad range of issues that affect the well-being of patients and their families, and strives to educate the public and government regulators on the basic principles of stem cell science and the realistic potential for new medical treatments and cures.

According to the ISSCR, when there is no existing or effective treatment for a disease or condition it is easy to understand why you may feel there is nothing to lose from trying something new, even if it isnt proven. Unfortunately, most of the unproven stem cell treatments for sale throughout the world carry very little promise of actual benefit and very real risks.

Many stem cell therapy clinics may offer the use of a patients own cells, also known an autologous transplant. In theory, your immune system would not attack your own cells if they were used in a transplant. However, the processes by which the cells were acquired, grown and then reintroduced into the body would carry risks. Here are just a few known risks of autologous stem cell treatments:

If you have thought about or are considering stem cell therapy, first get the guidance of your primary healthcare provider. They can help guide you in obtaining the right literature and evidence in help making the right decision for the safest and most effective treatments available. Snake oil salesmen exist in every industryincluding those wearing white lab coats. Choose your care wisely.

Stem cell therapy could be used to promote hair growth in people with either baldness or alopecia.

Stem cells may have a part to play in regrowing everything from teeth to eyeballs, and now researchers at UCLA are working on something that would be welcomed by people suffering from a very common problem regrowing hair in bald people. In new research, they describe a new way to activate the stem cells in the hair follicle to make new hair sprout. Such a breakthrough could potentially be used to develop drugs for promoting hair growth in people with either baldness or alopecia.

We found that hair follicle stem cells practice a distinct type of metabolism, and that if you fiddle with it genetically or pharmacologically, you can control the rate at which these cells wake up to make new hair shafts, Bill Lowry, a professor of molecular, cell, and developmental biology at UCLA, told Digital Trends.

Hair follicle stem cells generate hair over an individuals lifetime. These remain dormant much of the time, but activate quickly when a new hair cycle prompts growth. When they dont activate, baldness occurs.In small animal studies, the team was able to identify two drugs that influence hair follicle growth when applied to the skin. One drug is named RCGD423, and works by activating a cellular-signaling pathway that transmits information from outside the cell to the cells nucleus. The other drug, called UK5099, works by forcing the production of lactate in hair follicle stem cells, thereby accelerating hair growth.

We showed that drugs that promote production of a particular metabolite can accelerate hair follicle stem cell activation in mice, Lowry said. We are pushing forward toward the clinic to determine if this same approach is viable for human hair in patients with thinning due to stress, age, chemotherapy, [and] hormone imbalance.

There is still more work to be done before that point can be reached. As of now, the experimental drugs have not been tested in humans, nor approved as safe by the Food and Drug Administration. Researchers are optimistic that it will reach that point.We are considering starting a new company to support the ongoing development of new compounds that could be drugs for testing in a clinical trial, Lowry said.

A paper describing the research was recently published in the journal Nature Cell Biology.

Forever Labs, a startup in Y Combinators latest batch, is preserving adult stem cells with the aim to help you live longer and healthier.

Stem cells have the potential to become any type of cell needed in the body. Its very helpful to have younger stem cells from your own body on hand should you ever need some type of medical intervention, like a bone marrow transplant as the risk of rejection is greatly reduced when the cells are yours.

Mark Katakowski spent the last 15 years studying stem cells. What he found is that not only do we have less of them the older we get, but they also lose their function as we age.So, he and his co-founders Edward Cibor and Steve Clausnitzer started looking at how to bank them while they were young.

Clausnitzer banked his cells two years ago at the age of 38. So, while he is biologically now age 40, his cells remain the age in which they were harvested or as he calls it, stem cell time travel.

Steven Clausnitzer with his 38-year-old banked stem cells.

Stem cell banking isnt new. In fact, a lot of parents are now opting to store their babys stem cells through cord blood banking. But thats for newborns. For adults, its not so common, and theres a lot of snake oil out there, Clausnitzer cautions.

There are places offering stem cell therapy and Botox, he said.

Forever Labs is backed by a team of Ivy League-trained scientists with decades of experience between them. Jason Camm, chief medical officer for Thiel Capital, is also one of the companys medical advisors however, the startup is quick to point out it is not associated with Thiel Capital.

The process involves using a patented device to collect the cells. Forever Labs can then grow and bank your cells for $2,500, plus another $250 for storage per year (or a flat fee of $7,000 for life).

The startup is FDA-approved to bank these cells and is offering the service in seven states. What it does not have FDA approval for is the modification of those cells for rejuvenation therapy.

Katakowski refers to what the company is doing as longevity as a service, with the goal being to eventually take your banked cells and modify them to reverse the biological clock.

But that may take a few years. There are hundreds of clinical trials looking at stem cell uses right now. Forever Labs has also proposed its own clinical trial to take your stem cells and give them to your older cells.

Youll essentially young-blood effect yourself, Katakowski joked of course, in this case, youd be using your own blood made from your own stem cells, not the blood of random teens.

By: PTI | Los Angeles | Published:August 15, 2017 6:54 pm Understanding the critical role metabolism plays in hair growth and stem cells.

Scientists have discovered a new way to activate the stem cells in the hair follicle, an advance that may pave the way for novel drugs to promote hair growth. Hair follicle stem cells are long-lived cells in the hair follicle; they are present in the skin and produce hair throughout a persons lifetime. They are quiescent, meaning they are normally inactive, but they quickly activate during a new hair cycle, which is when new hair growth occurs.

The quiescence of hair follicle stem cells is regulated by many factors. In certain cases they fail to activate, which is what causes hair loss.

Researchers from University of California, Los Angeles in the US found that hair follicle stem cell metabolism is different from other cells of the skin. Cellular metabolism involves the breakdown of the nutrients needed for cells to divide, make energy and respond to their environment. The process of metabolism uses enzymes that alter these nutrients to produce metabolites.

As hair follicle stem cells consume the nutrient glucose a form of sugar from the bloodstream, they process the glucose to eventually produce a metabolite called pyruvate. The cells then can either send pyruvate to their mitochondria the part of the cell that creates energy or can convert pyruvate into another metabolite called lactate. Our observations about hair follicle stem cell metabolism prompted us to examine whether genetically diminishing the entry of pyruvate into the mitochondria would force hair follicle stem cells to make more lactate, and if that would activate the cells and grow hair more quickly, said Heather Christofk, an associate professor at UCLA.

The research team first blocked the production of lactate genetically in mice and showed that this prevented hair follicle stem cell activation. Conversely, they increased lactate production genetically in the mice and this accelerated hair follicle stem cell activation, increasing the hair cycle. Before this, no one knew that increasing or decreasing the lactate would have an effect on hair follicle stem cells, said William Lowry, a professor at the UCLA.

Once we saw how altering lactate production in the mice influenced hair growth, it led us to look for potential drugs that could be applied to the skin and have the same effect, said Lowry. The team identified two drugs that, when applied to the skin of mice, influenced hair follicle stem cells in distinct ways to promote lactate production.

The first drug, called RCGD423, activates a cellular signalling pathway called JAK-Stat, which transmits information from outside the cell to the nucleus of the cell. The research showed that JAK-Stat activation leads to the increased production of lactate and this in turn drives hair follicle stem cell activation and quicker hair growth. The other drug, called UK5099, blocks pyruvate from entering the mitochondria, which forces the production of lactate in the hair follicle stem cells and accelerates hair growth in mice.

Through this study, we gained a lot of interesting insight into new ways to activate stem cells, said Aimee Flores, first author of the study published in the journal Nature Cell Biology. The idea of using drugs to stimulate hair growth through hair follicle stem cells is very promising given how many millions of people, both men and women, deal with hair loss, said Flores.

I think weve only just begun to understand the critical role metabolism plays in hair growth and stem cells in general; Im looking forward to the potential application of these new findings for hair loss and beyond, she said.

Potential stem cell therapy may help promote hair growth - The Indian Express

BOSTON (AP) In his offices at Boston Childrens Hospital, Leonard Zon is busily developing cutting-edge stem cell therapies surrounded by fellow researchers, lab equipment and 300,000 striped, transparent zebrafish.

Zons lab and the zebrafish are the results of an initiative begun nearly a decade ago to make Massachusetts one of the countrys premier life sciences incubators.

That 2008 initiative, signed by former Democratic Gov. Deval Patrick, committed Massachusetts to spending $1 billion over 10 years to jump-start the life sciences sector attracting the best minds, research facilities and the venture capital funding.

By most yardsticks, Patricks gamble has paid off. Massachusetts, and the greater Boston area in particular, are now seen as a top life sciences hub.

For Zon, and other life sciences leaders, the support has been transformative.

In 2013, the Massachusetts Life Sciences Center, which is charged with disbursing the funds, awarded a $4 million grant to Childrens Hospital to help establish the Childrens Center for Cell Therapy. Some of the money went toward replacing the original aquaculture facilities at Zons lab with state-of-the-art systems.

Zon said the changes helped him pursue stem cell therapies taking tissues grown from stem cells aimed at thwarting specific diseases and transplanting them into a diseased organ. Zon said his lab helped develop a drug for treating a blood disease known as Diamond Blackfan anemia in part by developing zebrafish models of the disease.

Massachusetts is the best place in the world for biotechnology, he said. Its been life-changing for us.

Zons experience isnt unique.

NxStage Medical, Inc., a medical technology company founded in 1998 in Lawrence focused on end-stage renal disease and acute kidney failure, received nearly $1.8 million in tax incentives through the program. In 2013, Woburn-based Bio2 Technologies received $1 million in loan financing, helping it develop bone graft substitute implants.

The states reputation as a magnet for life sciences also can be seen in the surge of construction in Boston and Cambridge, particularly around the Kendall Square area, where glass-lined office and research buildings have sprouted.

Travis McCready, CEO of the Massachusetts Life Sciences Center, also pointed to the influx of grant money from the National Institutes of Health and funds from world-class academic and research institutions.

By pretty much any measure we are considered the leading life sciences ecosystem in the U.S., and among the leading ecosystems in the world, McCready said.

McCready said the 2008 initiative helped create a framework for that growth, even as he acknowledged that not every company or research effort that receives funding succeeds.

Some of these startups are going to fail, but ideas will be tested and intellectual property will be created, he said. Failure is not a negative.

McCready said a top goal of the program is to develop the next generation of researchers. The center funds over 500 life sciences internships each year with about a quarter of those landing full-time jobs at the company where they interned.

He said that talent pool is critical to the next stage in the life science revolution: bio-manufacturing and digital health.

Bio-manufacturing refers to the ability of research labs and life science companies to take their breakthroughs and start manufacturing them on a large scale. He pointed to a decision by Kendall Square-based Alnylam Pharmaceuticals to open a 200,000-square-foot (18,580 square meter) manufacturing space in Norton, just 45 minutes away.

He said the state also is hoping to builds up the digital health sector, where large sets of scientific data are used to look for new therapies and how best to deliver those medicines inexpensively.

Today we are the undisputed global leader in the field, Patrick said this week in a statement to The Associated Press. Public investment not only catalyzed hundreds of millions of dollars in private investment and created thousands of jobs, but contributes meaningfully to the development of life changing treatments and cures for people around the world.

Republican Gov. Charlie Baker is hoping to build on the initiative. In June, Baker announced a proposal to dedicate $500 million over five years to continue strengthening the life sciences with a focus on public infrastructure, research and development, workforce training and education. Baker said he will be supporting the public-private partnerships and strategic investments that have made Massachusetts a global leader in the life sciences.

What are the sources of stem cells and how do they differ?

And, how do you know what you're getting?

Plus, does stem cell therapy work?

These are common questions many people have about stem cell therapy.

Dan Schmidt and Dr. Steven Warren from Intermountain Stem Cells joined Midday to provide answers.

Stem Cell Therapy, particularly in the joints is being used more and more as an alternative to some surgeries. Stem cells help promote new natural growth of cartilage, ligament, tendons and soft tissue.

There are different sources of stem cells:

Stem cells are not all the same and delivered at the same qualities. Intermountain Stem Cell believes the best and most viable source of stem cell is umbilical cord MSC (Mesenchymal Stem Cells).

Intermountain Stem Cells say they've had significant patient outcomes and success in reducing pain and increasing functionality.

How do you know what you're getting with stem cell therapy? - Good4Utah

Cardiac stem cells derived from young hearts helped reverse the signs of aging when directly injected into the old hearts of elderly rats, astudypublished Monday in the European Heart Journal demonstrated.

The old rats appeared newly invigorated after receiving their injections. As hoped, the cardiac stem cells improved heart function yet also provided additional benefits. The rats fur fur, shaved for surgery, grew back more quickly than expected, and their chromosomal telomeres, which commonly shrink with age, lengthened.

The old rats receiving the cardiac stem cells also had increased stamina overall, exercising more than before the infusion.

Its extremely exciting, said Dr. Eduardo Marbn, primary investigator on the research and director of the Cedars-Sinai Heart Institute. Witnessing the systemic rejuvenating effects, he said, its kind of like an unexpected fountain of youth.

Weve been studying new forms of cell therapy for the heart for some 12 years now, Marbn said.

Some of this research has focused on cardiosphere-derived cells.

Theyre progenitor cells from the heart itself, Marbn said. Progenitor cells are generated from stem cells and share some, but not all, of the same properties. For instance, they can differentiate into more than one kind of cell like stem cells, but unlike stem cells, progenitor cells cannot divide and reproduce indefinitely.

From hisown previous research, Marbn discovered that cardiosphere-derived cells promote the healing of the heart after a condition known as heart failure with preserved ejection fraction, which affects more than 50% of all heart failure patients.

Since heart failure with preserved ejection fraction is similar to aging, Marbn decided to experiment on old rats, ones that suffered from a type of heart problem thats very typical of what we find in older human beings: The hearts stiff, and it doesnt relax right, and it causes fluid to back up some, Marbn explained.

He and his team injected cardiosphere-derived cells from newborn rats into the hearts of 22-month-old rats thats elderly for a rat. Similar old rats received a placebo injection of saline solution. Then, Marbn and his team compared both groups to young rats that were 4 months old. After a month, they compared the rats again.

Even though the cells were injected into the heart, their effects were noticeable throughout the body, Marbn said

The animals could exercise further than they could before by about 20%, and one of the most striking things, especially for me (because Im kind of losing my hair) the animals regrew their fur a lot better after theyd gotten cells compared with the placebo rats, Marbn said.

The rats that received cardiosphere-derived cells also experienced improved heart function and showed longer heart cell telomeres.

The working hypothesis is that the cells secrete exosomes, tiny vesicles that contain a lot of nucleic acids, things like RNA, that can change patterns of the way the tissue responds to injury and the way genes are expressed in the tissue, Marbn said.

It is the exosomes that act on the heart and make it better as well as mediating long-distance effects on exercise capacity and hair regrowth, he explained.

Looking to the future, Marbn said hes begun to explore delivering the cardiac stem cells intravenously in a simple infusion instead of injecting them directly into the heart, which would be a complex procedure for a human patient and seeing whether the same beneficial effects occur.

Dr. Gary Gerstenblith, a professor of medicine in the cardiology division of Johns Hopkins Medicine, said the new study is very comprehensive.

Striking benefits are demonstrated not only from a cardiac perspective but across multiple organ systems, said Gerstenblith, who did not contribute to the new research. The results suggest that stem cell therapies should be studied as an additional therapeutic option in the treatment of cardiac and other diseases common in the elderly.

Todd Herron, director of the University of Michigan Frankel Cardiovascular Centers Cardiovascular Regeneration Core Laboratory, said Marbn, with his previous work with cardiac stem cells, has led the field in this area.

The novelty of this bit of work is, they started to look at more precise molecular mechanisms to explain the phenomenon theyve seen in the past, said Herron, who played no role in the new research.

One strength of the approach here is that the researchers have taken cells from the organ that they want to rejuvenate, so that makes it likely that the cells stay there in that tissue, Herron said.

He believes that more extensive study, beginning with larger animals and including long-term followup, is needed before this technique could be used in humans.

We need to make sure theres no harm being done, Herron said, adding that extending the lifetime and improving quality of life amounts to a tradeoff between the potential risk and the potential good that can be done.

Capicor, the company that grows these special cells, is focused solely on therapies for muscular dystrophy and heart failure with ongoing clinical trials involving human patients, Marbn said.

Capicor hasnt announced any plans to do studies in aging, but the possibility exists.

After all, the cells have been proven completely safe in over 100 human patients, so it would be possible to fast-track them into the clinic, Marbn explained: I cant tell you that there are any plans to do that, but it could easily be done from a safety viewpoint.

About Medical Tourism Corporation (MTC)

The Texas-based Medical Tourism Corporation is a Better Business Bureau (BBB) accredited health tourism organizer. The corporation aims to connect medical tourists from all over the world to excellent healthcare services without the underlying stress. The most daunting part of the medical tourism process is the lack of information about quality treatments in Mexico, India, and other health tourism hubs. MTC emerges as a helping hand, and assists its customers in planning every little detail of their medical trip and even offers generous post-op services and follow-up care for a safe recovery.

With the introduction of alternative therapies for taxing and draining conditions, such as stem cells for Parkinson's in Mexico, the organization is expanding its arsenal of services and treatments offered.

Medical Tourism Corporation has recently partnered with GIOSTAR with the goal of making quality healthcare come true. The two entities have collaborated to offer personalized protocols for various conditions and injuries, including stem cell therapy for spinal injuries in Mexico.

Aiming to provide exemplary stem cell treatment in Mexico, MTC provides a host of services and features that set the venture apart:

What to Expect?

The National Institutes of Health (NIH) estimates up to 23.5 million Americans suffer from autoimmune diseases. All that is standing between these patients and life-altering medical treatments is a border away.

This timely collaboration between GIOSTAR and MTC is an important step forward in bridging the gap between demand and supply of effective alternative treatments for people suffering from the aforementioned ailments when conventional therapies fail to treat. More information on stem cell therapy in Mexico is available on the official website of Medical Tourism Corporation.

Cardiac stem cells rejuvenate rats' aging hearts, study says - CNN - CNN

Q: I read that you can use your own stem cells to rejuvenate worn-out knees. Does this really work?

A: Worn out is a good way to term what happens to the knee joint with prolonged use. Lets look at how this happens, starting with cartilage.

The lower portion of the knee joint (at the tibia) contains shock absorbers called menisci made of cartilage. You have one on the inner portion and another on the outer portion of each knee. The upper portion of the knee joint (at the femur) is lined with cartilage as well. All of this cartilage helps protect the bones at the joint but it doesnt heal or regenerate well due to limited blood supply. When severe, worn cartilage leads to arthritis of the knee. In knee X-rays of people over age 60, 37 percent have shown evidence of arthritis of the knees.

The intriguing thing about stem cells is that they have the ability to become any type of cell that the body needs. The cells used for stem cell injections in the knees are called mesenchymal stem cells, and they can differentiate into bone, fat or cartilage cells. These stem cells can come from the fat cells of your body, from your bone marrow or from the inner lining of your knee joint; theyre then replicated in the laboratory and injected into the knee joint.

Heres what the research shows so far.

In a 2013 study, 32 patients with meniscal tears of the knee were injected with a combination of stem cells, platelet-rich plasma and hyaluronic acid. The study reported improved symptoms and even MRI evidence of meniscal cartilage regeneration.

In a 2014 study, 55 patients who had surgery for meniscal tears of the knees were separated into three groups, with two of the groups receiving stem cell injections. Researchers found that, after six weeks, pain had decreased substantially in the two groups that received stem cell injections and that the decrease was even greater at one and two years after the injection.

In a 2017 study in the British Journal of Sports Medicine, researchers analyzed six studies that used stem cells for osteoarthritis of the knees. In five of the studies, stem cells were given after surgery to the knee; in the other study, stem cells from a donor were administered without surgery. All the studies showed reduced pain and improved knee function. Further, in three of the four trials, MRIs corroborated the cartilage improvements.

There may be benefit to stem cell injections for cartilage loss of the knees, but more data are needed. Id also like to see more data on this type of therapy as a preventive measure for younger patients before their knees are worn out.

The intriguing thing about stem cells is that they have the ability to become any type of cell that the body needs. The cells used for stem cell injections in the knees are called mesenchymal stem cells, and they can differentiate into bone, fat or cartilage cells. These stem cells can come from the fat cells of your body, from your bone marrow or from the inner lining of your knee joint; they're then replicated in the laboratory and injected into the knee joint.

Here's what the research shows so far ...

In a 2013 study, 32 patients with meniscal tears of the knee were injected with a combination of stem cells, platelet-rich plasma and hyaluronic acid. The study reported improved symptoms and even MRI evidence of meniscal cartilage regeneration.

In a 2014 study, 55 patients who had surgery for meniscal tears of the knees were separated into three groups, with two of the groups receiving stem cell injections. Researchers found that, after six weeks, pain had decreased substantially in the two groups that received stem cell injections and that the decrease was even greater at one and two years after the injection.

In a 2017 study in the British Journal of Sports Medicine, researchers analyzed six studies that used stem cells for osteoarthritis of the knees. In five of the studies, stem cells were given after surgery to the knee; in the other study, stem cells from a donor were administered without surgery. All the studies showed reduced pain and improved knee function. Further, in three of the four trials, MRIs corroborated the cartilage improvements. However, the authors noted, five of the six studies were of such poor methodology that an overall conclusion about the stem cells' effectiveness could not be made.

In all these studies, the most common side effect was knee swelling and stiffness, which improved over time.

There may be benefit to stem cell injections for cartilage loss of the knees, but more data are needed, especially in those who aren't having surgery of the knee. I'd also like to see more data on this type of therapy as a preventive measure for younger patients before their knees are worn out.

Researchers have created a method to kill cancerous tissue without causing the harmful side effects of chemotherapy.

Medical researchers at the University of California, Irvine have created a stem cell-based method to zero in on cancerous tissue. This method kills the cancerous tissue without causing the nasty side effects of chemotherapy. Such side effects are avoided by treating the disease in a more localized manner. The advancement was spearheaded by associate professor of pharmaceutical sciences Weian Zhao. The details of the stem cell therapy were recently published in Science Translational Medicine.

About the new Stem Cell Therapy

Zhao's team programmed stem cells derived from human bone marrow to pinpoint the specific properties of cancerous tissue. They implemented a portion of code to these engineered cells to identify stiff cancerous tissue, lock onto it and implement therapeutics. The researchers safely used this new stem cell therapy in mice to kill metastatic breast cancer that had moved to the lungs. They transplanted these engineered stem cells in order for the teamto pinpoint and settle in the site of the tumor.

Once the stem cells reached the tumor, they released enzymes referred to as cytosine deaminase. The mice were then provided with an inactive chemotherapy known as prodrug 5-flurocytosine. The tumor enzymes stimulated the chemotherapy into action. Zhao stated his team zeroed in on metastatic cancer that occurs when the disease moves to additional parts of the body. Metastatic tumors are especially dangerous. They are responsible for90 percent of all cancer deaths.

Why the new Stem Cell Therapy is Important

Zhao is adamant his stem cell therapy represents an important newparadigm in the context of cancer therapy. Indeed, Zhao has blazed a trail in a new direction that others will likely follow in the years to come. It is possible his new stem cell therapy serves as an alternative and more effective means of treating cancer. This stem cell therapy will serve as an alternative to numerous forms of chemotherapy that typically have nasty side effects. Chemotherapy certainly kills plenty of growing cancer cells yet it can also harm healthy cells. The new type of treatment keys in on metastatic tissue that allows for the avoidance of the undesirable side effects produced by chemotherapy.

Though the published piece describing this stem cell therapy is centered on breast cancer metastases within thelungs, the method will soon be applicable to additional metastases. This is due to the fact that numerous solid tumors are stiffer than regular tissue. The new system does not force scientists to invest time and effort to pinpoint and create a brand new protein or genetic marker for each kind of cancer.

The Next Step

At this point in time, Zhao's team has performed pre-clinical animal studies to show the treatment is effective and safe. They plan to segue to human studies in the coming months and years. Zhao's team is currently expanding to additional types of cells such as cancer tissue-sensing and engineered immune system CAR-T (T cells) to treat metastasizing colon and breast cancers. Their goal is totransform this technology for the treatment of additional diseases ranging from diabetes to fibrosis and beyond.

Stem Cell Therapy Selectively Targets and Kills Cancerous Tissue - Anti Aging News

In the days after a heart attack, surviving patients and their loved ones can breathe a sigh of relief that the immediate danger is over but the scar tissue that forms during the long healing process can inflict lasting damage. Too often it restricts the hearts ability to fill properly between beats, disrupting rhythm and ultimately leading to heart failure. Yet a new possible treatment may help to revitalize an injured ticker.

A cadre of scientists and companies is now trying to prevent or reverse cardiac damage by infusing a cocktail of stem cells into weakened hearts. One company, Melbourne, Australiabased Mesoblast, is already in late-stage clinical trials, treating hundreds of chronic heart failure patients with stem cell precursors drawn from healthy donors hip bones. A randomized trial that includes a placebo group is scheduled to complete enrollment next year.

Mesoblasts earlier-stage trials, published in 2015 inCirculation Research, found that patients who received injections of its cell mixture had no further problems related to heart failure.

Promising results from the new trial would be a major step forward for a field that has long been criticized for studies that are poorly designed, incomplete or lack control-group comparisons, as well as for the peddling of unproved therapies in many clinics worldwide.

Another company, Belgium-based TiGenix, hopes to attack scar tissue before it forms by treating patients with a mixture of heart stem cells within seven days of a heart attack. This approach has just completed phase II trials, but no findings have yet been published.

There are still many unanswered questions about how stem cells typically derived from bones could help heal the heart. Leading theories suggest they may help fight inflammation, revitalize existing heart cells, or drive those cells to divide or promote new blood-vessel growth, says Richard Lee, leader of the cardiovascular program at the Harvard Stem Cell Institute. Other stem cell scientists, including Joshua Hare, who conducted earlier-stage Mesoblast research and directs the Interdisciplinary Stem Cell Institute at the University of Miami, say the cells may work in multiple ways to heal scar tissue. According to Hare, the stem cells could ultimately be a truly regenerative treatment.

The one thing I still remember is us driving in our car and my daughter asking me, Mommy, am I going to die? West recounted.

Now an ardent advocate for stem cell therapy and storage, West, a product specialist for CryoSave, credits stem cells with saving her daughters life.

Her daughter needed a bone marrow transplant, which involved the transplanting of stem cells.

She found she was an exact donor match for her daughters bone marrow transplant - a one-in-a-million occurrence.

When youre faced with a situation such as that as a parent, you want and are willing to do anything to save your childs life I just want parents to understand what stem cells can do.

Fast forward 21 years and stem cells are revolutionising health care and through modern technology, parents can store their newborn babys umbilical cord stem cells in case of any future illnesses or health care needs.

Stem cells are present in the human body throughout life, constantly repairing tissue damaged by normal activity, the environment and other extraneous factors. They can replicate or regenerate themselves and have the ability to differentiate into any kind of specialised cell in the body.

Africa is the only continent without a public stem cell bank - private stem cell storage banks are in increasing demand as research and medical innovation has shown that many blood cancers, blood disorders, autoimmune diseases and immunodeficiencies are treatable with cord blood.

Umbilical cord blood and stem cell banking is still a relatively novel concept in South Africa.

However, new parents are increasingly opting to have their newborn babies stem cells extracted from their umbilical cords.

According to CryoSave - which stores 7 800 client stem cell samples - the process is simpler and quicker than one might expect.

Once the baby is born, the umbilical cord is clamped and cut as per normal in any birth. It is only after this that the blood and tissue are collected from the cord - which is usually discarded as medical waste after the birth.

A babys umbilical cord stem cells are a 100% perfect match and biological parents stem cells will be at least a half-match.

There is a 25% probability of matching siblings and, unlike bone marrow transplants, one doesnt have to have a perfect match in transplants when making use of cord blood stem cells.

Today, umbilical cord blood stem cells are used in more than one-third of all blood stem cell transplants in the world.

Explaining the process behind the storage of umbilical cord cells at their labs, Christiene Botha, a lab quality manager said: The blood we receive goes through a rigorous sterilising, processing and freezing process.

The samples are then stored in liquid nitrogen tanks at a temperature of -196C.

But time is of the essence in this process.

The umbilical cord blood sample needs to reach the lab within 48 hours - and the cut off is at 64 hours - as blood cells start dying after 72 hours.

Depending on what product one uses to store the cells, storage rates can be from R250 to R300 a month.

The fact that we dont have a public national bank puts us at a disadvantage because it is the ideal. So there arent many choices for parents out there - but families can look after themselves through this type of storage.

"My daughter is 30-years-old, is married and lives a full life because of stem cells, West concluded.

It's a cancer of the plasma cells, which normally make an array of antibodies that protect us from infection.

With multiple myeloma, the cells start primarily producing instead a singular product, called a monoclonal antibody, or M spike, that leaves patients vulnerable for serious infections, like pneumonia, and can even eat away at their bones.

Sophisticated laboratory tests used to both diagnose the disease then follow treatment response, can send confusing messages to patients and their physicians, particularly after stem cell therapy to try to restore a healthy antibody mix, says Dr. Gurmukh Singh. Singh, vice chair of clinical affairs for the Department of Pathology and Walter L. Shepeard Chair in Clinical Pathology at the Medical College of Georgia at Augusta University, is corresponding author of the study highlighting reasons for potential confusion in the Journal of Clinical Medicine Research.

The tests, serum protein electrophoresis and serum immunofixation electrophoresis, or SPEP/SIFE, and serum free light chain assay, or SFLCA, separate proteins into groups according to their electrical charge.

The M spike stands out as a distinctive, dense band of color among the layers of protein groups, while typical antibody levels create bands of lighter smears.

But after stem cell therapy, which first destroys cancerous plasma cells then restores healthy ones, follow up profiles often yield a lineup of antibodiescalled an oligoclonal patternthat can look eerily similar to the M spike.

The confusion comes because there again may be a prominent and likely short-lived band of proteins that emerges as the antibody mix begins, ideally, to normalize.

"We want to emphasize that oligoclonal bands should mostly be recognized as a response to treatment and not be mistaken as a recurrence of the original tumor," Singh says.

The key clarifier appears to be the location of the malignant, monoclonal spike when the diagnosis is made compared to the location of new spikes that may show up after stem cell therapy in these oligoclonal bands, says Singh.

"If the original peak was at location A, now the peak is location B, that allows us to determine that it is not the same abnormal, malignant antibody," Singh says, pointing toward different before and after treatment profiles on a patient.

Normally antibodies spread out in a usual sequence in these studies. "If it's in a different location, it's not the same protein," reiterates Singh. "If the location is different, this is just a normal response of recovery of the bone marrow that could be mistaken for recurrence of the disease," Singh says of the oligoclonal bands that can also temporarily show up in response to an infection.

He notes while the prominent bands are typically short-lived following treatment, the recognition that they are non-malignant may occur only in retrospect.

For the study, Singh and his team looked at lab and clinical data on 251 patients with multiple myeloma treated from January 2010 to December 2016; 159 of those patients received autologous stem cell transplants. Each patient had at least three tests, and at least two of the tests were following their transplant.

They found the incidence of oligoclonal patterns was significantly higher in patients who had a stem cell transplant than the patients who had chemotherapy alone: 57.9 percent compared to 8.8 percent. Only five of the 159 patients who received a transplant had an oligoclonal pattern before treatment but 92 had one afterward. More than half of the the oligoconal patterns developed within the first year following a transplant. The earliest pattern was detected at two months - as soon as the first post-transplant tests were doneand a few occurred as long as five years later.

Autologous stem cell therapy is not considered curative for most patients with multiple myeloma. There is no clear cause of the disease but the risk does increase at age 40, Singh says.

Advancellssays its stem cell-based therapy completely reversed multiple sclerosis (MS) in an Indian pilot trial with only one MS patient.

The patient, Rahul Gupta, was diagnosed with MS seven years ago and has since suffered multiple relapses. His disease was progressing fast and he was quickly losing his ability to walk. Gupta, who lives in New Zealand, approached Advancells a company based in the Indian state of Uttar Pradesh that specializes in the use of stem cells for therapeutic purposes.

After my last relapse, I became determined to look for alternative treatments for multiple sclerosis,Gupta said in a press release. I started looking on the net and found that stem-cell therapy [offers] hope for people suffering with MS [and] that it is safe and would not harm me in any way. I was determined to undergo stem-cell treatment, as my illness was progressing very quickly.

Gupta enrolled inAdvancells adult stem-cell therapy program as the trials single patient. In the procedure carried outin June at a New Delhi clinic doctors isolated stem cells from his bone marrow and re-infused them back into the patientat specific points. Apart from this procedure, Gupta underwent only physiotherapy and a dietary routine.

Straight after the treatment I saw major improvements, he said. I could walk a lot better, could climb stairs which I was unable to do after 2012 and even go on the treadmill.

Dr. Lipi Singh, head of technology at Advancells, said the company is frequently approached by MS patients from around the world who want to participate in its program.

Patient selection is a key criterion for us and Rahul suited the criteria perfectly, Singh said. He is young and still at a moderate level of the disease and in a very positive frame of mind. Patients at this stage are best suited for this kind of treatment and thus we decided to accept him as a pilot case.

Singh now expects to review Guptas response sometime this fall.

It will take approximately three months for us to review changes in the magnetic resonance imaging of the patient, but the drastic changes in symptoms clearly are an indication of the fact that the treatment is working and could become a hope for millions of patients across the world who are suffering from this disease. Singh said.

He added: This is a good start to a lengthy research phase, but it seems that we are on the right track and hopefully we will be able to make a significant contribution in eradicating not only MS but a host of untreatable diseases existing today.

An Odessa physician who specializes in pain management has begun offering stem cell therapy for inflammation from a variety of arthritis.

Dr. Mandeep Othee of ProCare Interventional Pain Medicine, said stem cell therapy has been around since as early as 1938. It has recently been used to stem inflammation, wound care and post-surgical use to help in healing.

The purpose for me is going to be for inflammation for knee arthritis, shoulder arthritis any sort of arthritic process in the neck, the back; any part of the body, Othee said.

Othee said hes always interested in cutting-edge treatments. As associate medical director of In-Patient Rehabilitation at Medical Center Hospital, Othee oversees care for patients with a variety of orthopedic needs, ranging from stroke patients to those recovering from joint replacement surgery, the hospital website said.

He also specializes in diagnosing and treating neck and low-back pain.

The source of the amniotic stem cells is healthy women who have had C-sections who donate their amniotic fluid to a tissue bank. Othee said it is fully regulated by the U.S. Food and Drug Administration and the cells are purified and frozen to preserve them.

The cells provide cushioning, support and lubrication to a developing fetus in the womb.

Its a similar process in the body, so for example, if we take that same stem cell and inject it into the patients knee, or shoulder, or back, or neck it provides the same cushioning, support, lubrication and inflammation reduction that it does in the developing fetus, Othee said.

He added that there are 226 growth factors in the fluid itself, which includes proteins, lipids electrolytes and the magic element of hyaluronic acid.

Thats the typical injection a patient receives in an orthopedic surgeons office. It basically heals the area, provides collagen synthesis and helps with the re-growth of that lost cartilage , Othee said.

Cartilage wears down over time in the joints and injecting the stem cells greatly increases the patients own healing response. Othee said it works 100,000 times better than Platelet Rich Plasma, which is taking a patients own platelets, spinning it down, putting it into a concentrated format and injecting into the patients knee, shoulder, neck or back, Othee said.

Typically, Othee said hes read studies have shown 30, 90 and 100-day responses that are better than steroid shots or hyaluronic acid injections.

It can help patients avoid or delay joint replacement surgeries.

The product he chose is OrthoFlo made by MiMedx.

I chose them because theyre the biggest and the best, Othee said. Their company specializes in different products. One is OrthoFlo. It contains pro-growth factors (and) no tissue fragments or dead cells. It is highly purified human amniotic fluid.

He noted that thousands of injections have been administered over the last five to 15 years and no reactions, side effects or infections have been reported that hes read about.

Currently, no insurance companies pay for the stem cell therapy, but athletes have been getting these for years in other countries, such as Germany and England, and larger cities such as Houston and Dallas. The cost is $2,200 per injection from Othee.

The patient may be sore for a day or two after the stem cell injection and they are able to walk out of the office without a problem. For any sort of knee injections, Othee said a patient may want to wait a week to start running or doing other activities.

Othee said he usually asks patients to stop taking anti-inflammatory medicine for at least seven days before and after the treatment.

He added that there is no age limit on people who could receive stem cell therapy.

Othee said patients may have tried steroid shots, hyaluronic acid, or platelet rich plasma before stem cell therapy. However, they could skip right to stem cell therapy, he added.

Othee said he has spoken to other doctors with patients who have gone straight to stem cell therapy and it works.

Orthopedic surgeon Dr. Vijay Borra doesnt do stem cell injections. He said he thinks research into stem cells just as an injection for osteoarthritis is still in its infancy.

I think a lot of research now is going into using stem cells to generate chondrocytes, which are cartilage to see if we can plug in focal cartilage deficits. Thats where all the research is now. As far as just injecting stem cells into the joint, were still at the very early stages and theres still very little data as to whether it actually works or not, Borra said.

Borra added that there is a lot of good data using that to generate cartilage.

Theres some data there can be used to plug defects. Its an option for people who have done everything like a steroid or hyaluronic gel injections. Theyve done all that and they dont want a knee replacement, or they have too many medical issues and theyre not a candidate. Then it is an option. If theres nothing else, then stem cell is an option, Borra said.

He added that stem cell therapy is not covered by most insurance plans and the out-of-pocket pay is very high.

Its really like an end-stage resort for someone who doesnt want surgery. Theres really no down side. Its not going to do any damage, so you can always try to see if it helps, Borra said.

When patients come to see him, Borra said he first gives them an x-ray to see what the problem is. Most of the time, its osteoarthritis.

By the time they come to Borra, he said the patient has tried anti-inflammatories, weight loss and therapy.

Theyve already done all that, so I start off with a steroid injection. If it works five, six months some people choose to do two or three a year. If it doesnt work, the next option is gel injections, hyaluronic acid, which is like artificial joint fluid, Borra said.

He said Othee also offers nerve blocks.

Odessa physician offering stem cell therapy - Odessa American: News - Odessa American

For patients with severe and end-stage heart failure there are few treatment options left apart from transplants and stem-cell therapy. But a new Israeli study finds that stem-cell therapy may harm heart-disease patients.

The research, led by Prof. Jonathan Leor of Tel Aviv Universitys Sackler Faculty of Medicineand Sheba Medical Center and conducted by TAUs Dr. Nili Naftali-Shani, explores the current practice of using cells from the host patient to repair tissue and contends that this can prove toxic for patients.

We found that, contrary to popular belief, tissue stem cells derived from sick hearts do not contribute to heart healing after injury, said Leor. Furthermore, we found that these cells are affected by the inflammatory environment and develop inflammatory properties. The affected stem cells may even exacerbate damage to the already diseased heart muscle.

Tissue or adult stem cells blank cells that can act as a repair kit for the body by replacing damaged tissue encourage the regeneration of blood vessel cells and new heart muscle tissue. Faced with a worse survival rate than many cancers, many heart-failure patients have turned to stem-cell therapy as a last resort.

But our findings suggest that stem cells, like any drug, can have adverse effects, said Leor. We concluded that stem cells used in cardiac therapy should be drawn from healthy donors or be better genetically engineered for the patient.

The researchers, who published their study in the journal Circulation, also discovered the molecular pathway involved in the negative interaction between stem cells and the immune system as they isolated stem cells in mouse models of heart disease. Afterward, they focused on cardiac stem cells in patients with heart disease.

The results could help improve the use of autologous stem cells those drawn from the patients themselves in cardiac therapy, Leor said.

We showed that the deletion of the gene responsible for this pathway can restore the original therapeutic function of the cells, said Leor. Our findings determine the potential negative effects of inflammation on stem-cell function as theyre currently used. The use of autologous stem cells from patients with heart disease should be modified. Only stem cells from healthy donors or genetically engineered cells should be used in treating cardiac conditions.

The researchers are currently testing a gene editing technique (CRISPER) to inhibit the gene responsible for the negative inflammatory properties of the cardiac stem cells of heart disease patients. We hope our engineered stem cells will be resistant to the negative effects of the immune system, said Leor.

A new treatment currently undergoing human clinical trials could see the end of pin prick tests for diabetics (Credit: bacho123456/Depositphotos)

A human clinical trial examining the safety and efficacy of a "functional cure" for type 1 diabetes is currently underway. Trials of the novel islet cell replacement therapy developed by ViaCyte involve a device containing stem cells being implanted into a patient with type 1 diabetes. It's hoped these cells will then mature into human islet tissue with insulin-producing beta cells that produce insulin on demand.

So far, 2017 is proving to be an exciting year for breakthroughs in diabetes research, particularly in regards to treatments for type 1 diabetes. We have seen two very promising developments based in gene therapy, while a human trial for a type 1 diabetes vaccine is currently underway in Finland targeting a viral group known to trigger the disease.

UPGRADE TO NEW ATLAS PLUS

The new treatment developed by ViaCyte is being described as a "functional cure" in that it could replace the missing insulin cells in a diabetic patient, as opposed to a more direct "cure" which would address the autoimmune roots of the disease.

The treatment being trialed piggybacks off prior working knowledge of islet cell transplantation being successful in patients with type 1 diabetes. For some time, patients with the disease have been treated with pancreatic cells from organ donors, successfully liberating them from insulin injections.

"Islet transplants have been used to successfully treat patients with unstable, high-risk type 1 diabetes, but the procedure has limitations, including a very limited supply of donor organs and challenges in obtaining reliable and consistent islet preparations," says trial investigator James Shapiro. "An effective stem cell-derived islet replacement therapy would solve these issues and has the potential to help a greater number of people."

The new treatment involves a device called PEC-Direct, which holds stem cell-derived pancreatic progenitor cells and is implanted into a patient. This allows those cells to mature in the body, becoming islet tissue that includes the beta cells that produce insulin when needed.

Because these stem cells can be replicated in a laboratory, this process doesn't rely on a finite amount of organ donor cells and allows the treatment to be delivered to a large number of patients quickly and easily. Unlike current similar treatments, which require invasive transplantation directly into the liver, this new device can be easily implanted superficially under the skin.

The first patients being implanted with small-format versions of the devices will evaluate the safety of the treatment. A second, larger cohort will be recruited later in 2017 to also evaluate its safety and also ascertain the treatment's efficacy. If implantation and cell maturation is demonstrated, the trials will measure how much clinically relevant insulin is being delivered by the treatment.

This new strategy being trailed by ViaCyte is hoped to have demonstrable and definite efficacy within the next two years, meaning the practical deployment may not be too far away if all goes well.

As well as the PEC-Direct for treating type 1 diabetes, the company is also developing a broader device called PEC-Encap, which could be used to treat all patients with diabetes who use insulin, type 1 and type 2. If these trials are successful they could prove to be a watershed moment in the treatment of diabetes.
