摘要: 为骨骼肌卫星细胞自体移植治疗心肌疾病准备细胞材料;建立了体外分离、纯化、培养、扩增骨骼肌卫星细胞的方法。用机械法结合酶消化法分离犬骨骼肌卫星细胞,经Percoll非连续密度梯度离心纯化过程后,以Desmin链霉素抗生物素—过氧化酶免疫细胞化学染色鉴定。以完全培养液加用扩增卫星细胞。提取的卫星细胞纯度在90%以上,且证明促肝细胞生长素能增强细胞的增殖能力。表明此法可获得高纯度及治疗所需细胞数量。

Abstract: The authors had isolated skeletal muscle satellite cells by mechanic and enzymic digestion,purified them by Pecoll discontinuous density gradient centrifugation and identified them immunocytochemically by Desmin-labeling,and multiplied the satellite cells by administration of promoting heptocyte growth factor (pHGF). The purity of harvested satellite cells exceeded 90%.It was suggested that the pHGF was usful for prompting satellite cell growth by shortening the lag period and enhancing their proliferation capacities.
