Sex-based differences in Muscle Stem Cell Regulation Following Exercise

Abstract:Sexual dimorphism, driven by the sex hormones testosterone and estrogen, influences body composition, muscle fiber type, and inflammation. Research related to muscle stem cell (MuSC) responses to exercise has mainly focused on males. We propose a novel hypothesis that there are sex-based differences in MuSC regulation following exercise, such that males have more MuSCs while females demonstrate a greater capacity for regeneration.
