Number of human myofibers per xenograft. The scattergram shows the distribution of the total number of engrafted human muscle fibers in each graft following hMPC transplantation, determined by counting the number of fibers labeled with antibodies to human β-spectrin in cross sections. Only one graft with human tissue, containing 39 human myofibers, was obtained from a total of 18 mice in group 1. Groups 2 and 3 showed more grafts with higher numbers of muscle fibers of human origin, with a range of 13–145 and 22–226 myofibers per cross section sampled, respectively. Differences between groups were significant by t tests (#p < 0.01; *p < 0.05; **p < 0.001)
