Excellent long-term survival (up to 1 yr) of donor skeletal muscle cells was demonstrated using a mouse Y-chromosome specific probe, following the transplantation of grafts of whole muscles from male ''normal'' C57BI/10Sn mice into dystrophic muscles of female host mice. After the transplantation of equivalent sliced muscle grafts there was extensive movement of the male donor cells and fusion with host myofibres. This contrasts with the extremely poor survival of isolated myoblasts after injection into the same mouse model for Duchenne muscular dystrophy. The use of sliced muscle grafts may therefore represent a potential alternative approach to myoblast transfer therapy.
