Figure 5. A slow fiber type switch in regenerating Hq muscles.
Quantification of fibers expressing type I, type II, embryonic and neonatal MyHC in WT and Hq soleus (A, C, E, G) and EDL (B, D, F, H) muscles 3 (A, B), 5 (C, D), 10 (E, F) and 20 (G, H) days following cardiotoxin injury indicates a slow fiber type switch and an increase in immature regenerating myofibers in Hq mice, the latter corroborating the delay in skeletal muscle regeneration of Hq mice. * indicates P<0.05 vs WT.
