Exercise rejuvenates muscle stem cells in older mice

Exercise helps muscle stem cells in old mice to regain youthful qualities

Researchers at Stanford School of Medicine found that a nightly trip on the exercise wheel improved muscle repair in older mice.

Researchers found that this benefit was only seen in older mice. This is because the muscle stem cells of the animals were rejuvenated.

Thomas Rando, MD and Ph.D. Professor of Neurology and Neurological Sciences and Director of Stanford’s Glenn Center for the Biology of Aging, said that the effect on old animals was very significant. We found that regular physical activity restores youthfulness in tissue repair. Their muscle stem cell appearance and behavior start to resemble that of younger animals.
