Adult Stem Cells And Cancer Risk

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 »

A number of articles have seen print this week about the possible cancer risk from adult stem cells; a team has demonstrated the ability of lab-cultured adult stem cells to become cancerous after many months of cultivation. This has always been regarded as a low level potential risk, but as this BBC piece notes, "stem cell lines maintained and developed in stem cell banks over a long period of time are currently only used for research purposes. They are not transplanted into people." Still, this shows that much more research into cellular behavior would be a good thing. That understanding feeds into many different fields: regenerative medicine, cancer research and aging research amongst them.
