Dedifferentiation Progress

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 »

(From EurekAlert). A privately funded venture claims significant progress towards dedifferentiating blood cells into stem cells and then using them to build tissue. We've heard this before to no great result, but it'll be the real deal sooner rather than later: "The idea is to revert a patient's blood cells to the stem cell stage and then chemically nudge them to re-specialise into particular tissue types that can be implanted to heal damaged tissue. A huge advantage over using donated tissue is that the transplant would be 'autologous' - made of the patient's own cells, thus avoiding immune rejection ... [Pharmafrontiers] now claims to have refined a way to produce stem cells from white blood cells called monocytes and develop them into many different tissue types including, crucially, insulin-producing cells."
