Researchers rejuvenate stem cell population from elderly mice, enabling muscle recovery

Researchers have pinpointed why normal aging is accompanied by a diminished ability to regain strength and mobility after muscle injury: over time, stem cells within muscle tissues dedicated to repairing damage become less able to generate new muscle fibers and struggle to self-renew. Scientists identified for the first time a process by which the older muscle stem cell populations can be rejuvenated to function like younger cells.
