Mitochondrial Transfer as Healing?

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 most interesting New Scientist article looks at hints of an existing mechanism by which age-damaged mitochondria could be repaired. Given the central role played by mitochondrial degeneration in aging, this would be a very big deal if it could be exploited: "Healthy cells seem to have shown an amazing ability to breathe new life into damaged ones by rejuvenating their defunct mitochondria. It is an extraordinary and controversial claim. But if confirmed it could offer a way to prevent a range of harrowing metabolic diseases that affect millions of people. Experts in mitochondrial research have yet to be convinced. They say the work purporting to show the effect has yet to be comprehensively peer-reviewed, and is so potentially ground-breaking that more evidence is needed."
