Abstract

目的 比较脂肪基质干细胞(ASC)与骨髓基质干细胞(MSC),为ASC的细胞移植治疗提供实验依据.方法分离培养脂肪组织来源的ASC、分离培养骨髓组织来源的MSC,培养至14 d时,对贴壁细胞再次计数,当细胞融合达到80%时,胰蛋白酶消化传代培养,取第3~4代细胞进行分析.观察培养前后两种细胞的形态并计数,流式细胞仪分析两种细胞的表面抗原表达,混合淋巴细胞反应及淋巴细胞转化实验比较两种细胞的免疫原性.结果ASC与MSC细胞表面抗原表达基本相似,但也存在差别,ASC为CD49d+CD106-,而MSC为CD49d-CD106+.ASC与MSC都能抑制淋巴细胞增殖,且这种抑制作用与其数量呈正相关.但相同数量的ASC和MSC对淋巴细胞的抑制作用无明显差别.结论ASC和MSC在细胞表面抗原、免疫原性等方面相似,这为进一步利用ASC移植治疗疾病的研究提供了依据。
