Insulin-like growth factor 1 and muscle growth: implication for satellite cell proliferation.
Insulin-like growth factor 1 (IGF-1) has been shown to rescue the aging-related or inactivity-induced loss of muscle mass through the activation of satellite cells. However, the signalling pathways and the mechanism by which IGF-1 affects satellite cells have not been not completely identified. The purpose of the present review is to provide current understanding of the cellular and molecular events underlying IGF-1 induced proliferation of satellite cells.
