图1. 骨骼肌卫星细胞形态
A：刚分离的骨骼肌卫星细胞呈球形,折光性强;B：部分卫星细胞开始细胞贴壁,向四周延展;C：分离培养48 h卫星细胞呈梭形或纺锤形;D：分离培养72 h卫星细胞数量增加出现汇合;E：细胞生长至70%时的形态;F：培养5 d细胞拉长变细呈有规律排列;G：培养7 d卫星细胞自发融合,形成多核肌管;H：复苏第3次传代后冻存的骨骼肌卫星细胞

Fig. 1. The morphology of skeletal muscle satellite cells (100×)
A: The separated skeletal muscle satellite cells are spherical and have strong refractive index; B: Some satellite cells begin to adhere and extend to the periphery; C: 48 h of satellite cells are fusiform or spindle-shaped; D: Separated and cultured for 72 h. The number of satellite cells increased and converged; E: Morphology of cells growth to 70%; F:Cells elongated and thinned regularly after cultured 5 days; G: 7 days of satellite cells spontaneously fused to form multinucleated myotubes; H: Recovery skeletal muscle satellite cells frozen after 3 passages
