Comparisons of eight different muscle groups from 4-month- and 2-year-old male Pax7-ZsGreen mice. a Quantification of the number of satellite cells in eight different muscle groups by FACS. b Measured muscle mass in milligrams. c Number of satellite cells normalized to muscle mass. Data shown are mean ± SE (n=6, except diaphragm where n=4). Results of p-value comparisons performed using two-tailed t tests are indicated above each graph
