Stem cells need recovery time, too

Researchers’ strategy may help rejuvenate aging muscle tissue

Is aging inevitable? What factors make older tissues in the human body less able to maintain and repair themselves, as in the weakening and shrinkage of aging muscles in humans? A new study from Harvard-affiliated Massachusetts General Hospital (MGH) investigators and collaborators at King’s College London describes the mechanism behind impaired muscle repair during aging and a strategy that may help rejuvenate aging tissue by manipulating the environment in which muscle stem cells reside. The report will appear in the journal Nature and has received advance online release today.
