  1. All values are presented as mean ± SEM. One-way repeated measures ANOVA for main effects, Fisher’s least significant difference for post-hoc comparisons. For any technique, there was no significant difference between age groups. %Diff for 0.8 Power: percent difference required to obtain 80% power between age groups for a satellite cell identification technique
  2. EM electron microscopy, LM light microscopy, DL dystrophin–laminin immunohistochemistry
  3. * DL was significantly different from electron microscopy, light microscopy, and MyoD immunohistochemistry (P < 0.001)
