Myoblasts, the precursors of skeletal muscle fibers, can be induced to withdraw from the cell cycle and differentiate in vitro. Recent studies have also identified undifferentiated subpopulations that can self-renew and generate myogenic cells (Baroffio, A., M. Hamann, L. Bernheim, M.-L. Bochaton-Pillat, G. Gabbiani, and C.R. Bader. 1996. Differentiation. 60:47–57; Yoshida, N., S. Yoshida, K. Koishi, K. Masuda, and Y. Nabeshima. 1998. J. Cell Sci. 111:769–779). Cultured myoblasts can also differentiate and contribute to repair and new muscle formation in vivo, a capacity exploited in attempts to develop myoblast transplantation (MT) for genetic modification of adult muscle. Our studies of the dynamics of MT demonstrate that cultures of myoblasts contain distinct subpopulations defined by their behavior in vitro and divergent responses to grafting. By comparing a genomic and a semiconserved marker, we have followed the fate of myoblasts transplanted into muscles of dystrophic mice, finding that the majority of the grafted cells quickly die and only a minority are responsible for new muscle formation. This minority is behaviorally distinct, slowly dividing in tissue culture, but rapidly proliferative after grafting, suggesting a subpopulation with stem cell–like characteristics.

Human myoblasts were transplanted in nude mice. The efficacy of these transplantations was analyzed using a monoclonal antibody (NCLDys3) specific for human dystrophin. This antibody did not reveal any dystrophin in nude mice that did not receive a human myoblast transplantation. However, about 30 days after a human myoblast transplantation, dystrophin-positive muscle fibers were observed. They were not abundant, and were present either in small clusters or isolated. This technique follows the fate of myoblast transplantation in animals that already have dystrophin, and distinguishes between new dystrophin-positive fibers due to the transplantation and the revertant fibers in mdx mice. Moreover, this technique does not require any labelling of the myoblasts before transplantation. It can also be used to detect dystrophin produced following the fusion of myoblasts transfected with the human dystrophin gene.
