摘    要:目的文献报道大鼠骨髓间充质干细胞(MSCs)不表达CD45,而本实验中却发发现CD45高度表达,针对这一现象做初步分析:方法成体大鼠骨髓MSCs的分离培养,对原代、第3代和第6代细胞做流式细胞仪检测MSCs的表面标记物以及染色体分析。结果体外培养的大鼠骨髓MSCs呈长梭型、有突起,排列成旋涡状。流式细胞仪检测示原代细胞:CD29(99.9%),CD90(48.5%),CD45(996%),CD34(202%);第3代细胞:CD29(100%),CD90(97.1%),CD45(100%),CD34(089%);第6代细胞:CD29(99.7%),CD90(99.6%),CD45(99.7%),CD34(0.49%)。上述3代细胞的染色体分析床细胞核型为二倍体。结论体外培养的成体大鼠骨髓MSCs同时表达CD29,CD90和CD45,不表达CD34。

Abstract:Objective Currently reported in the literature that rat bone marrow mesenchymal stem cells(MSCs) did not express CD45,but our experiment found a high degree expression of CD45.So we try to analyse this phenomenon.Methods MSCs were isolated and cultured from adult rat bone marrow.The original passage,passage3 and passage 6 of the MSCs were tested by flow cytometry to characterize their surface antigen expression.Results The cultured MSCs were fusiform and had protrusions,arranged in spiral-shaped.The tests o...
