Each mouse injected with SSP cells represents an independent experiment. Total, total number of fibers per section; Max D+, maximum number of dystrophin-positive fibers per section; D+Y+, dystrophin-positive fibers that contain at least one Y-chromosome-positive nucleus as determined by FISH; SSP, skin SP; SMP, skin MP.
