This is a technology platform with some potential: &#8220;combining gene therapy with tissue engineering could avoid the need for frequent injections of <a href=\"http:\/\/en.wikipedia.org\/wiki\/Recombinant_DNA#Applications_of_recombinant_DNA_technology\">recombinant drugs<\/a>. Patients who rely on recombinant, protein-based drugs must often endure frequent injections, often several times a week, or <a href=\"http:\/\/en.wikipedia.org\/wiki\/Intravenous_therapy\">intravenous therapy<\/a>. Researchers [have demonstrated] the possibility that blood vessels, made from genetically engineered cells, could secrete the drug on demand directly into the bloodstream. &#8230; Such drugs are currently made in <a href=\"http:\/\/en.wikipedia.org\/wiki\/Bioreactor\">bioreactors<\/a> by engineered cells, and are very expensive to make in large amounts. &#8230; The paradigm shift here is, &#8216;why don&#8217;t we instruct your own cells to be the factory?&#8217; &#8230;  [Researchers] provide proof-of-concept, reversing <a href=\"http:\/\/en.wikipedia.org\/wiki\/Anemia\">anemia<\/a> in mice with engineered vessels secreting <a href=\"http:\/\/en.wikipedia.org\/wiki\/Erythropoietin\">erythropoietin (EPO)<\/a>. &#8230; The researchers created the drug-secreting vessels by isolating endothelial colony-forming cells from human blood and inserting a gene instructing the cells to produce EPO. They then added <a href=\"http:\/\/en.wikipedia.org\/wiki\/Mesenchymal_stem_cell\">mesenchymal stem cells<\/a>, suspended the cells in a gel, and injected this mixture into the mice, just under the skin. The cells spontaneously formed networks of blood vessels, lined with the engineered <a href=\"http:\/\/en.wikipedia.org\/wiki\/Endothelium\">endothelial cells<\/a>. Within a week, the vessels hooked up with the animals&#8217; own vessels, releasing EPO into the bloodstream. Tests showed that the drug circulated throughout the body and reversed anemia in the mice.&#8221;<\/p>\n<p><span>Link: <a href=\"http:\/\/www.marketwatch.com\/story\/engineered-drug-secreting-blood-vessels-reverse-anemia-in-mice-2011-11-15\">http:\/\/www.marketwatch.com\/story\/engineered-drug-secreting-blood-vessels-reverse-anemia-in-mice-2011-11-15<\/a><\/span><\/p>\n<p>Source:<br \/><a href=\"http:\/\/www.longevitymeme.org\/newsletter\/latest_rss_feed.cfm\">http:\/\/www.longevitymeme.org\/newsletter\/latest_rss_feed.cfm<\/a><\/p>\n<p>Source:<br \/><a href=\"http:\/\/www.longevitymedicine.tv\/feed\/\">http:\/\/www.longevitymedicine.tv\/feed\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you can build new living tissue to be implanted in patients, then why not also give it the capacity to perform additional useful tasks?
