Fig. 5From: Differential requirement for satellite cells during overload-induced muscle hypertrophy in growing versus mature miceDynamic continuum of satellite cell (SC) participation in overload-induced muscle fiber hypertrophy throughout the lifespan. Satellite cells are required for hypertrophic growth in young adult mice (2.5Â months of age), are not required for hypertrophic growth in mature adult mice (>4Â months of age), and are not permissive for hypertrophy in aged anabolic resistant mice (>24Â months of age, refer to Lee et al. [41]). CSA cross-sectional areaBack to article page
