(SACRAMENTO, Calif.) UC Davis investigators have found new evidence that a promising type of stem cell now being considered for a variety of disease therapies is very similar to the type of cells that give rise to cancer. The findings suggest that although the cells -- known as induced pluripotent stem cells (iPSCs) -- show substantial promise as a source of replacement cells and tissues to treat injuries, disease and chronic conditions, scientists and physicians must move cautiously with any clinical use because iPSCs could also cause malignant cancer.

The article, "Induced pluripotency and oncogenic transformation are related processes," is now online in the journal, Stem Cells and Development.

"This is the first study that describes the specific molecular pathways that iPSCs and cancer cells share from a direct comparison" said Paul Knoepfler, associate professor of cell biology and human anatomy, and principal investigator of the study. "It means that much more study is required before iPSCs can be used clinically. However, our study adds to a growing knowledge base that not only will help make stem cell therapies safer, but also provide us with new understandings about the cancer-causing process and more effective ways to fight the disease."

Since 2007, cell biologists have been able to induce specialized, differentiated cells (such as those obtained from the skin or muscle of a human adult) to become iPSCs. Like embryonic stem cells, iPSCs are a type of stem cell that is able to become any cell type. This "pluripotent" capability means that iPSCs have the potential of being used in treatments for a variety of human diseases, a fundamentally new type of clinical care known as regenerative medicine.

iPSCs are considered particularly important because their production avoids the controversy that surrounds embryonic stem cells. In addition, iPSCs can be taken from a patient's own skin and induced to produce other needed tissues, thereby evading the possibility of immunologic rejection that arises when transplanting cells from a donor to a recipient. In contrast to therapies based on ES cells, iPSCs would eliminate the need for patients to take immunosuppressive drugs.

Earlier research indicated that both ES cells and iPSCs pose some health risks. Increasing evidence suggests that pluripotency may be related to rapid cellular growth, a characteristic of cancer. iPSCs, as well as embryonic stem cells, are well known by scientists to have the propensity to cause teratomas, an unusual type of benign tumor that consists of many different cell types. The new UC Davis study demonstrates for the first time that iPSCs -- as well as ES cells -- share significant similarities to malignant cancer cells.

The investigators compared iPSCs to a form of malignant cancer known as oncogenic foci that are also produced in laboratories; these cell types are used by medical researchers to create models of cancer, particularly sarcoma. Specifically, the scientists contrasted the different cells' transcriptomes, comprised of the RNA molecules or "transcripts." Unlike DNA analysis, which reflects a cell's entire genetic code whether or not the genes are active, transcriptomes reflect only the genes that are actively expressed at a given time and therefore provide a picture of actual cellular activity.

From this transcriptome analysis, the investigators found that the iPSCs and malignant sarcoma cancer cells are unexpectedly similar in several respects. Genes that were not expressed in iPSCs were also not expressed in the cancer-generating cells, including many that have properties that guide a cell to normally differentiate in certain directions. Both cell types also exhibited evidence of similar metabolic activities, another indication that they are related cell types.

Researchers find multiple similarities between cancer cells and induced pluripotent stem cells

Knoepfler noted, for example, that future experimental therapies using iPSCs for human transplants would most often not involve implanting iPSCs directly into a patient. Instead, iPSCs would be used to create differentiated cells -- or tissues -- in the laboratory, which could then be transplanted into a patient. This approach avoids implanting the actual undifferentiated iPSCS, and reduces the risk of tumor development as a side effect. However, Knoepfler noted that even trace amounts of residual iPSCs could cause cancer in patients, a possibility supported by his team's latest research.

Multiple similarities discovered between cancer cells and induced pluripotent stem cells

By Jeffrey M. O'Brien, contributor

Stem cells stored in liquid nitrogen at Advanced Cell Technology in Marlborough, Mass.

FORTUNE -- Imagine yourself the proud but rueful owner of an ancient Jaguar. Every day you dread the uncertainty that comes with trying to get from here to there -- there, more often than not, being the shop. No sooner does one ailment find repair than another appears. At best, it's a slow, uncomfortable ride. Lonely too. There's really no one around who fully understands your plight.

That is how Patricia Riley describes life in a 95-year-old body. Riley, who reached that milestone birthday last St. Patrick's Day, lives alone in the same 1,100-square-foot house in Plainfield, Conn., that she's called home for 64 years, having survived her husband (heart disease), a daughter (breast cancer), and every friend she ever had. "All the people I knew have all gone, Jeffrey," she says in a quivering voice laced with melancholy. "They've all died. I go to church and I never see people my age." Her remaining family includes two daughters, five grandchildren, and eight great-grandchildren, including my two young sons. In a nod to her French-Canadian heritage, we call her Mme.

Mme attributes her longevity to good genes, but she clearly owes a debt to modern medicine. Over the years she's had a cholecystectomy, a hysterectomy, esophageal surgery, a stroke, and ulcerative colitis. Lately she relies on a cane and a walker, and her daily regimen includes pain pills for arthritis, two inhalers for asthma, high-blood-pressure meds, a statin, vitamins, digestion aids, and an anti-anxiety drug that she calls "my nerve pill." Her vision also comes courtesy of medical science. Three years ago Mme was diagnosed with a form of age-related macular degeneration, or AMD, a disease of the back of the retina that is the leading cause of vision loss in the developed world. The ophthalmologist gave her a choice: a needle into her eyeballs every six weeks, or blindness. Mme opted for the injections and now receives shots of an off-label cancer drug called Avastin, which has demonstrated efficacy in halting the progress of her type of AMD. Holding the ailment at bay is all she can hope for. "I'll have to go for as long as I live," she says. "It's just a treatment -- it's not a cure."

Treatments, not cures. This, in a nutshell, is the MO of our health care system, and it's precisely the reason that regenerative medicine -- and stem cell therapy in particular -- has been the subject of so much hope and hype over the past decade or so. Stem cell therapies promise to empower a body to fight ailments by enabling it to build new parts. Think about growing new neurons or heart tissue. Think about the difference between perpetually slathering that old Jag with Bondo and having it heal itself overnight in the garage.

MORE:Stem cell dollars: California leads the way

While stem cells have ignited plenty of religious outrage and political grandstanding, behind the headlines the underlying science has been advancing the way science often does -- by turns slowly and dramatically. To be clear, the earliest stem cell therapies are almost certainly years from distribution. But so much progress has been made at venerable research institutions that it now seems possible to honestly discuss the possibility of a new medical paradigm emerging within a generation. Working primarily with rodents in preclinical trials, MDs and Ph.D.s are making the paralyzed walk and the impotent virile. A stem cell therapy for two types of macular degeneration recently restored the vision of two women. Once they were blind. Now they see! Some experts assert that AMD could be eradicated within a decade. Other scientists are heralding a drug-free fix for HIV/AIDS. Various forms of cancer, Parkinson's, diabetes, heart disease, stroke, and ALS have already been eradicated in mice. If such work translates to humans, it will represent the type of platform advancement that comes along in medicine only once in a lifetime or two. The effect on the economy would be substantial. Champions of stem cell research say it would be on the order of the Internet or even the transistor.

The obstacles along the road from lab rat to human patients are many, of course, but the biggest by far is money. With the dramatic events in the lab, you might think that a gold rush would be under way. That's far from true. Long time horizons, regulatory hurdles, huge R&D costs, public sentiment, and political headwinds have all scared financiers. Wall Street isn't interested in financing this particular dream. Most stem cell companies that have dared go public are trading down 90% or more from their IPOs. Sand Hill Road is AWOL. The National Venture Capital Association doesn't even have a category to track stem cell investments.

Big Pharma would seem to be the most obvious benefactor. The drug companies understand the complexities (and billion-dollar outlays) involved in bringing therapies to market. A few drug companies have kicked the tires on stem cells over the years, but waiting for them to undo the current model is akin to banking on Big Oil to rethink energy. They may do it, but it's unlikely to be by choice. Which leaves stem cell researchers begging for state and federal grants at a time scientific funding is under siege.

The great stem cell dilemma

CARLSBAD, CA--(Marketwire - Sep 25, 2012) - International Stem Cell Corporation ( OTCQB : ISCO ) (www.internationalstemcell.com) ("ISCO" or "the Company") a California-based biotechnology company, today announced that the United States Patent and Trademark Office (USPTO) has granted the Company a patent for a method of creating pure populations of definitive endoderm, precursor cells to liver and pancreas cells, from human pluripotent stem cells.This patent is a key element of ISCO's metabolic liver disease program and allows the Company to produce the necessary quantities of precursor cells in a more efficient and cost effective manner.

The patent, 8,268,621, adds to the Company's growing portfolio of proprietary technologies relating to the development of potential treatments for incurable diseases using human parthenogenetic Stem Cells (hpSC).Human parthenogenetic stem cells are unique pluripotent stem cells that offer the possibility to reduce the cost of health care while avoiding the ethical issues that surround the use of fertilized human embryos.Aside from the Company's current liver disease program, this new patented method can be used as a route to create pancreatic and endocrine cells that could be used in future studies of diabetes and other metabolic disorders.

ISCO currently has the largest collection of hpSC including cell lines which immune match the donor, as is the case with induced pluripotent stem cells (iPS), and cell lines which immune-match millions of individuals and potentially reduce tissue rejection issues.The Company is focusing its therapeutic development efforts on three clinical applications where cell and tissue therapy is already proven but where there currently is an insufficient supply of safe and efficacious cells: Parkinson's disease, inherited/metabolic liver diseases and corneal blindness.

About International Stem Cell Corporation

International Stem Cell Corporation is focused on the therapeutic applications of human parthenogenetic stem cells (hpSCs) and the development and commercialization of cell-based research and cosmetic products.ISCO's core technology, parthenogenesis, results in the creation of pluripotent human stem cells from unfertilized oocytes (eggs) hence avoiding ethical issues associated with the use or destruction of viable human embryos.ISCO scientists have created the first parthenogenetic, homozygous stem cell line that can be a source of therapeutic cells for hundreds of millions of individuals of differing genders, ages and racial background with minimal immune rejection after transplantation. hpSCs offer the potential to create the first true stem cell bank, UniStemCell. ISCO also produces and markets specialized cells and growth media for therapeutic research worldwide through its subsidiary Lifeline Cell Technology (www.lifelinecelltech.com), and stem cell-based skin care products through its subsidiary Lifeline Skin Care (www.lifelineskincare.com).

Cancer, induced pluripotent stem cell similarities

NOKOMIS, Fla.--(BUSINESS WIRE)--

As Rainbow BioSciences, the biotech subsidiary of Rainbow Coral Corp. (RBCC), works to acquire licensing for commercial use of NASA-developed stem cell expansion technology, the company received good news from a Wall Street analysts forecast on Wednesday.

Writing for Seeking Alpha, George Kesarios predicted major growth for the global stem cell market in coming years. Its estimated that the market will be worth about $64 billion by 2015, up from $21.5 billion in 2010.

Kesarios attributed the growth largely to a potential revolution in drug companies research and development made possible by an abundance of induced pluripotent stem cells.

With these stem cells, scientists can actually create working facsimiles of living human tissue, introduce diseases and observe how they unfold under a microscope, said RBCC CEO Patrick Brown. Spending a decade on research only to discover in trials that a drug doesnt work could become a thing of the past. Stem cells hold the key to the future of profitable, effective drug development.

Thats why RBCC has engaged Regenetech in discussions regarding the potential acquisition of a license to perform cell expansion using that companys Rotary Cell Culture SystemTM.

The Rotary Cell Culture SystemTM is a rotating-wall bioreactor designed to facilitate the growth of human cells in simulated weightlessness. Cell cultures, including stem cells, grown inside the bioreactor look and function much closer to human cells grown within the body than the flat cell cultures grown in Petri dishes.

The potential for stem cells expansion using this unique culturing system originally devised for the space program is incredible, Brown said. Every cell researcher in the world is going to want access to this technology.

RBCC plans to offer new technology to compete in the stem-cell research industry alongside Amgen, Inc. (AMGN), Celgene Corporation (CELG), Genzyme Corp. (NASDAQ:GENZ) and Gilead Sciences Inc. (GILD).
