Abstract: In this study, mouse skeletal muscle satellite cells were isolated by collagenase and trypsinase digestion method. Then the satellite cells were purified and induced to differentiate into myotubes, and the marker genes of the cells before or after the differentiation were detected by RT-PCR and immunocytochemistry technology. The results show that the isolated muscle satellite cells were healthy, and expressed the marker genes of paired protein box (Pax7) and myogenic differentiation antigen (MyoD). After inducing to the myotubes, myogenin (MyoG) and myosin heavy chain (MHC)showed positive expression. The results indicate that mouse skeletal muscle satellite cells of high purity, which can provide cell sources for muscle development and damage repair study, are successfully isolated.
