Stem Cells To Overcome Aging

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 EMBO Reports, an excellent article (and some bold claims) on the prospects for stem cell research and regenerative medicine to overcome age-related degeneration: "All ageing phenomena - tissue deterioration, cancer and propensity to infections - can be interpreted as signs of ageing at the level of somatic stem cells. As the regenerative prowess of a living organism is determined by the ability and potential of its stem cells to replace damaged tissue or worn-out cells, a living organism is therefore as old as its stem cells. ... an understanding of the molecules and processes that enable stem cells to initiate self-renewal and to divide, proliferate and then differentiate to rejuvenate damaged tissue might be the key to regenerative medicine and an eventual cure for many diseases."
