Pericytes may improve muscle recovery: Pericyte transplantation may improve skeletal muscle recovery following limb immobilization, animal study shows

Extended periods of limb immobilization — whether from long-term bed rest, casting, spaceflight, or other circumstances — can reduce skeletal muscle mass and strength to the extent that recovery is delayed or never achieved. The biological basis for this lack of recovery, however, remains unclear. An animal study published in…
