摘要: [摘 要] 目的:建立分离并鉴定人骨髓间充质干细胞(HMSC)的方法。 方法:联合应用Percoll(1.073 g•L-1)密度梯度离心和贴壁筛选的方法分离HMSC进行体外培养,利用免疫细胞化学、细胞化学和电镜等技术手段对体外培养的HMSC进行鉴定。 结果:HMSC具有独特的表型特征,即CD29、CD44阳性和CD34、CD45阴性。细胞糖原反应(PAS)阳性、苏丹黑反应(SB)阴性。电镜观察结果提示细胞较幼稚。 结论:利用密度梯度离心和贴壁筛选的方法可以分离HMSC,联合应用免疫细胞化学、细胞化学和电镜等技术手段鉴定HMSC的方法有效。

Abstract: Objective To establish a method to isolate and identify human mensenchymal stem cells(HMSC). Methods The HMSC were isolated and cultured in vitro by applying methods of density-grad centrifugal and anchoring screening. The immunocytochemistry, cytochemistry, and electron microscopy were used to identify HMSC cultured in vitro. Results The HMSC have particular phenotype:CD29 and CD44 were positive,CD34 and CD45 were negative.PAS was positive,and SB was negative.HMSC were infantile under electron microscope. Conclusion The HMSC can be isolated with density-grad centrifugal and anchoring screening. The method to identify HMSC with immunocytochemistry, cytochemistry and electron microscopy is effective.
