Posthatch muscle growth through the process of
hypertrophy is mediated by the adult myoblast stem
cell population termed satellite cells. The satellite cells
were first identified by Mauro (1961) as being located
between the basement membrane and sarcolemma of
skeletal muscle fibers. Muscle growth through hypertrophy
occurs by the satellite cells fusing with and donating
their nuclei to existing muscle fibers (Stockdale
and Holtzer, 1961; Moss and LeBlond, 1971), increasing
protein synthesis potential.
