Figure 5. Morphological analysis of the mdx EDL.

Figure 5

(a) In the mdx 4H group, the mean fiber size of myosin heavy chain (MHC) type IIA and IIB fibers increased which led to an overall increase in total fiber size. (b) At eleven months of age, the mdx 11H group did not demonstrate fiber size differences of either fiber type or total fibers compared to controls. (c) The number of fibers in the midbelly cross section of the EDL in all treated groups was not different from respective control fiber number. (d) There were 11% more type IIB fibers in the mdx 4H group while in the mdx 11L and 11H groups there were 16–19% more type IIB fibers. Data represent mean±SD. * Statistically significant compared to control, p<0.05.
