Figure 8.

Representative images for fiber typing (stained with lead nitrate-ATPase method described by Rosenblatt) and capillarity (stained with FIT-C labeled Griffonia isolectin B4) in mouse skeletal muscle. For fiber typing, darkly stained fibers are type I (as shown by the white arrow) and lightly stained are type II (as shown by the black arrow). Red arrows show examples of capillaries in lectin stained images. GA-d, gastrocnemius muscle deep; GA-s, gastrocnemius muscle superficial; SOL, soleus; EDL, extensor digitorum longus; Mb^−/−, myoglobin knockout; PLT, plantaris; WT, wild type.
