摘要
目的:观察接触式细胞共培养条件下,人髓核细胞对脐带华通胶间充质干细胞(Wharton′s jelly-derived mesenchymal stem cells,WJMSCs)的诱导分化效应,为椎间盘退变性疾病的治疗寻找种子细胞来源。方法:取足月产健康新生儿脐带约30cm,分离、纯化、培养WJMSCs;取人椎间盘髓核组织,酶消化法分离培养髓核细胞。取第三代稳定增殖的WJMSCs,利用流式细胞方法检测细胞免疫表型CD73/CD90/CD105/CD34/CD45/HLA-ABC/HLA-DR。用羧基荧光素乙酰乙酸琥珀酰亚胺酯(CFSE)标记WJMSCs,与髓核细胞以1∶1比例进行混合,在6孔板中进行接触式细胞共培养;以单独培养的WJMSCs为对照组。培养7d后利用高速流式细胞仪分选荧光标记阳性的WJMSCs,提取细胞总RNA,进行反转录获得cDNA,利用Real-Time PCR方法检测其Ⅰ型胶原、Ⅱ型胶原、Ⅵ型胶原、蛋白多糖、SOX-9和多能聚糖基因的相对表达,管家基因GAPDH作为内参,单独培养的WJMSCs作为对照,利用2-ΔΔCt方法计算基因相对表达变化。结果:WJMSCs原代细胞接种24h可见部分细胞贴壁生长,形态为梭形和多角形,1周后形成集落,2周时细胞融合达到90%。流式细胞检测结果显示CD73/CD90/CD105/和HLA-ABC(+),CD34/CD45和HLA-DR(-)。与髓核细胞共培养7d后WJMSCs的Ⅱ型胶原、蛋白多糖和SOX-9基因相对表达较对照组显著性增加(P<0.01),Ⅰ型胶原、Ⅵ型胶原和多能聚糖基因相对表达未见显著性变化(P>0.05)。结论:通过接触式细胞共培养人脐带WJMSCs能够被髓核细胞诱导分化为类髓核细胞,可为组织工程技术和细胞治疗修复退变椎间盘提供种子细胞来源。
