Clonal analyses of muscle-derived cells from HC transplant xmd recipients. Donor or recipient origin of the muscle-derived cell clones was determined by VNTR analyses. Fibroblast (A) or muscle clones (B) were isolated, harvested, and assayed by VNTR analyses (C). The arrows in panel C refer to the donor-specific bands in the satellite cell clones revealing a mixed genotype in 5 of the clones with donor contributions ranging from 2% to 35% (a = 10%, b ≤ 5%, c ≤ 5%, d ≤ 5%, and e = 20%).
