title: Allografts of muscle precursor cells persist in the non-tolerized host.
abstract: Implantation of normal muscle precursor cells into myopathic fibres to alleviate recessively inherited diseases of skeletal muscle has received much attention since the discovery of a defective or deficient gene coding for the protein dystrophin in the Duchenne and Becker forms of muscular dystrophy. Therapeutic allografting of cells would require some means of preventing their immune rejection. Here we have allografted muscle into the non-tolerant and non-immunosuppressed murine host. Precursor cells introduced in the form of a single cell suspension survive for prolonged periods post-implantation. Allografts of minced muscle often failed to survive, even though host and donor were compatible at the major histocompatibility locus. Differences at minor loci may well have contributed to such rejection. Where allografted tissue was rejected, there was a decrease in the amount of surviving host muscle at the graft site, an important observation in terms of the therapeutic implantation of cells.
