Another Advance In Reprogramming Cells

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

As ScienceDaily notes, researchers "report having achieved what has long been a dream and ultimate goal of developmental biologists - directly turning one type of fully formed adult cell into another type of adult cell. ... the team is able to turn mouse exocrine cells, which make up about 95 percent of the pancreas, into precious and rare insulin-producing beta cells. ... Unlike the process involved in creating induced pluripotent stem cells (iPS) [this] direct reprogramming technique does not require turning adult cells into stem cells and then figuring out how to induce them to differentiate into a desired cell type. ... We're intrigued by the possibility that this approach, which has worked for pancreatic insulin-producing cells, could be more widely applied to many kind of cells, especially those that are lost in disease or following injury. And at the same time, we are exploring the possibility of using this general approach in a clinical context to make new beta cells for patients."
