摘要
目的 :体外定向诱导成人骨髓间质干细胞 (MSC)分化为脂肪细胞。方法 :采用Ficoll-Paque淋巴细胞分离液 (1 0 77× 10 3 g/L)离心分离成人MSC ,体外扩增 ,流式细胞仪检测MSC表面抗原表达 ,地塞米松、IBMX、胰岛素、indomethacin定向诱导MSC分化为脂肪细胞。油红O检测中性脂肪 ,光镜下细胞计数。结果 :成人骨髓间质干细胞在体外扩增 5代可获得 1× 10 8个细胞。流式细胞仪检测结果显示CD2 9、CD44、CD90、CD10 5、CD16 6表达阳性 ,CD14、CD34、CD45、CD11a为阴性。诱导 48h后 ,细胞内有脂滴出现 ,随着时间延长 ,脂滴逐渐增加并融合为脂泡。细胞由梭形转变为圆形或多角性。细胞计数结果显示 85 %以上细胞转变为脂肪细胞。结论 :成人骨髓间质干细胞在体外可以分化为脂肪细胞。
