Researchers have determined that exercise affects the behavior of your muscle stem cells. This finding could lead to new techniques to rehabilitate injured muscle, or to prevent or restore age-related muscle loss.
It has long been known that mesenchymal stem cells (MSCs) in skeletal muscle are an important part of the muscle repair process. The scientists discovered that MSCs in muscle are very responsive to mechanical strain.
According to Fight Aging:
“They witnessed MSC accumulation in muscle of mice after vigorous exercise ... Preliminary data suggest MSCs become deficient in muscle with age. The team hopes to develop a combinatorial therapy that utilizes molecular and stem-cell-based strategies to prevent age-related muscle loss.”
