Early sarcomere formation. Confocal images of regenerating zones of human single muscle fibres at 7 days post injury, where immature actin striations (phalloidin, red) were clearly visible within a desmin+ (green) filamentous sheath (a) or within a CD56+ membrane (b). The nuclei (blue) are likely to be myonuclei. Note part of the adjacent undamaged fibre at the bottom of the image in a, where the mature striation pattern of the sarcomere can be seen. The dashed line indicates the location of the YZ orthogonal view. Scale bars, 20 μm
