ALT Figure 1A: Myofiber growth and myonuclear positioning during late embryonic and early postnatal development. (A) Representative images of cross-sectioned gastrocnemius muscle from E17.5, P1, P3, P5, P7 and P20 mice, stained for syntrophin to label the sarcolemma (white) and for DAPI to label nuclei (cyan). Magnifications corresponding to the yellow squares are shown on the right of each image. Individual channels of the magnified views are shown in Fig. S2. Scale bars: 50 µm.
