Proliferating cells and myotubes. Confocal images of a long regenerating zone (arrows) of a human skeletal muscle fibre, lying above an uninjured fibre, stained for the myogenic marker CD56 (red), cell proliferation marker Ki67 (green) and nuclei (blue). a scale bar, 100 μm. The areas indicated by the dashed line box were imaged at higher magnification, shown in b, where images are displayed as maximum intensity projections of multiple or single stack slices. CD56+ myogenic cells and myotubes (arrowhead) are visible. Asterisk indicates a single CD56+ satellite cell on the undamaged fibre. b Scale bars, 20 μm
