Normal fiber-type distributions in extensor digitorum longus and soleus muscles of six-week-old Pparδ -cKO mice. (A) through (D) Immunostained sections showing the distribution of fiber types in the extensor digitorum longus (EDL) and soleus (SOL) ("C-" denotes wild-type littermate control and "M-" denotes Pparδ-cKO): myosin heavy chain isoform 1 (MyHC-1) (red), MyHC-2a (blue), MyHC-2b (green), MyHC-2x (black) and laminin (white). The basal lamina surrounding each fiber is shown. Scale bar = 1 mm. (E) Percentage distribution of each fiber type in the EDL and SOL muscles (N = 4 pairs of littermates.
