The morphological and microstructural analyses of gastrocnemius muscle. (a) The gross observation of the gastrocnemius muscles in the control, PNI, vehicle, and FGF13 groups at week 6 after the transection. (b) H&E staining of the cross-sections of the muscles in the four groups. Scale . (c) Quantification of the relative muscle weight from (a). (d) Quantification of the positive area of muscle fibers in the indicated groups from (b). Values are expressed as , . vs. the control group; ^& and ^&& vs. the PNI group; ^# and ^## vs. the PNI group.
