"Exercised-induced myocyte disruptions are not repaired in diabetic mice. A: Paired transmission and fluorescence micrographs showing EBD-labeled myofibers (arrows) in the gastrocnemius muscle from diabetic (INS2) and control (Ctl) (B6) mice that run downhill for 60 min and then are injected with the EBD tracer. Myocytes that were injured by running and failed to repair are labeled. B: The number of EBD myofibers counted from such micrographs in the gastrocnemius and quadriceps muscles of diabetic INS2 and control B6 mice. Data are presented as the mean ± SEM. *P < 0.05; n = 5 mice for the ""Run"" groups and 4 mice for the ""Not Run"" groups. Scale bar, 100 μm and 20× magnification. (A high-quality digital representation of this figure is available in the online issue.)"
