| Outline of Final Research Achievements |
Skeletal muscle contains stem cell population called satellite cells. Satellite cells can generate myotube in vitro but there is a critical difference between myotube and skeletal muscle tissue. In addition, use of human cells is needed for the medical research. It is possible that making human muscle fibers in vivo by transplanting human satellite cells into the muscles of immunodeficient mice. However, it is difficult to achieve efficient transplantation of human satellite cells because purification method of human satellite cells has not been established. In this study, we discovered novel marker of human satellite cells, CD82. We demonstrated that efficient transplantation of human satellite cells into immunodeficient mice can be done by utilizing CD82 as a positive selection marker. We believe that our results provide useful information for the study of human skeletal muscle cells.
