Abstract |
Satellite cells are mononucleated cells of the skeletal muscle lineage that exist beneath the basal lamina juxtaposed to the sarcolemma of skeletal muscle fibers. It is widely accepted that satellite cells mediate skeletal muscle regeneration. Within the satellite cell pool of adult muscle are skeletal muscle stem cells (MuSCs), also called satellite stem cells, which fulfill criteria of tissue stem cells: They proliferate and their progeny either occupies the adult MuSC niche during self-renewal or differentiates to regenerate mature muscle fibers. Here, we describe robust methods for the isolation of enriched populations of human satellite cells containing MuSCs from fresh human muscle, utilizing mechanical and enzymatic dissociation and purification by fluorescence-activated cell sorting. We also describe a process for xenotransplantation of human satellite cells into mouse muscle by injection into irradiated, immunodeficient, mouse leg muscle with concurrent notexin or bupivacaine muscle injury to increase engraftment efficiency. The engraftment of human MuSCs and the formation of human muscle can then be analyzed by histological and immunofluorescence staining, or subjected to in vivo experimentation. |
