About this episode
This episode discusses the regenerative potential of skeletal muscle in microgravity and its implications for aging.
Skeletal muscle is one of the most abundant tissues in the human body, representing approximately 40% of body weight. Under certain circumstances, skeletal muscle can be regenerated through satellite cells, a reservoir of quiescent muscle stem cells, that can be activated with injury or in certain diseases and give rise to newly formed multi-nucleated myotubes and myofibers. However, the regenerative potential of muscle is diminished or is completely absent in the course of normal aging, cert...
