FIG. 7.

Native and stained cross-sections of murine hindlimb muscle. Serial 8 μm-thick cryosections of (a) native, (b) SDH-stained, and (c) MyHC-specific-stained skeletal muscles (I: MyHC 1 [red]; IIa: MyHC 2a [green]; IId: MyHC 2d/x [unstained/black]; IIb: MyHC 2b [blue]) revealing the fiber-type distribution as well as their oxidative capacity (SDH stain). Bars = 100 μm. MyHC, myosin heavy chain; SDH, succinate dehydrogenase. To see this illustration in color, the reader is referred to the web version of this article at www.liebertpub.com/ars
