Objective: To culture the myoblast of neonatal mice's in vitro, and to observe the biology feature of morphology.Methods: Separating skeletal muscle of neonate mice, and cultured in vitro. Myoblast were primarily cultured in vitro with DMEM/F-12 culture liquid. Myogenesis of biology feature and ultrastructure were observed by phase contrast and TEM .The distribution of its structure protein was detected by immunocytochemistry. Results: Digested by collagenase and trypsin and cultured by differential a...
