To delineate the cellular and molecular cascades orchestrating skeletal muscle repair, focusing on satellite cell dynamics and the supportive contribution of adult stem cells.
Synthesized molecular and histological evidence on mammalian skeletal muscle response to acute necrosis and injury.
Assessed activation trajectories of myogenic satellite cells, myogenic regulatory factor induction, and extrinsic stem cell recruitment.
Muscle injury initiates necrosis and an inflammatory cascade, promptly followed by satellite cell activation, proliferation, differentiation, and fusion into functional myofibers.
Regenerative activation closely recapitulates embryonic myogenesis through the de novo induction of myogenic regulatory factors driven by local signaling cues.
Non-muscle adult stem cells, including bone marrow-derived and muscle-derived stem populations, contribute to myofiber synthesis and replenish the resident satellite cell reservoir.
