摘要(Abstract):
[目的]建立肌卫星细胞和肌内前体脂肪细胞的共培养体系。[方法]用10μg/ml INS、1μmol/L DEX和115 ng/ml IBMX对北京油鸡肌肉SV细胞进行诱导后,通过油红染色法、细胞免疫学鉴定及关键基因的表达对诱导的SV细胞进行分析。[结果]油红O脂肪染色法鉴定结果表明,诱导后的细胞红色脂质密度较高,说明SV细胞经过诱导后含有更多的前体脂肪细胞。通过实时荧光PCR定量检测细胞发育的标志性基因,发现诱导与未诱导的肌肉SV细胞均会表达前体脂肪细胞标志性基因。[结论]肌肉SV细胞经过诱导后前体脂肪细胞的含量得到提高,有利于建立前体脂肪细胞和肌卫星细胞的体外培养体系。
