More Evidence for Muscle Stem Cell Activity to be Inhibited by the Aged Tissue Environment (opens in new tab)

Stem cells support tissues by generating a supply of daughter somatic cells to replace losses. A broad body of evidence points to reduced muscle stem cell activity as a major contributing cause of age-related loss of muscle mass and strength. Other evidence suggests that this stem cell population remains capable; when old muscle stem cells are removed from the aged tissue environment for assessment, they appear to be as capable as young muscle stem cells. Researchers are now interested in est...
