It is known that skeletal muscle regeneration is impaired in age-related diseases such as sarcopenia, which is marked by reduced muscle regenerative capacity with aging, due in part to a reduction in muscle stem cells or satellite cells. This is also the case with adult late-onset myopathies, including limb girdle muscular dystrophy.  However, it is unclear how this loss of satellite cells occurs.  Now, a … Continue reading Study identifies gene responsible for regeneration of injured muscle by adult stem cells.
