摘要:

背景:体外分离培养骨髓间充质干细胞成为实验研究和临床应用的关键环节。
目的:采用全骨髓培养法分离人骨髓间充质干细胞,建立一种简单、有效的分离培养骨髓间充质干细胞的方法。
方法:通过全骨髓培养法分离培养人骨髓间充质干细胞,并通过传代进行纯化和扩增培养。分别在特定诱导体系中诱导人骨髓间充质干细胞向脂肪、成骨及软骨细胞分化。
结果与结论:采用全骨髓培养分离法能获得90%以上纯度的骨髓间充质干细胞;流式细胞仪检测结果显示,贴壁细胞均表达CD73、CD90、CD105,不表达造血细胞表型CD34、CD45和HLA-DR;细胞倍增时间为(24.04±0.49) h;细胞周期分析表明:G0~G1期和S+G2+M期所占比例分别为71.63%和28.37%;诱导分化结果显示,人骨髓间充质干细胞能够向脂肪、骨和软骨细胞分化。说明全骨髓分离培养法是一种较好的分离人骨髓间充质干细胞的方法。

Abstract:

Abstract
BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) are widely used in cell therapy and tissue regeneration, so their isolation and culture are a key technique for research and clinical application.
OBJECTIVE: To isolate the BMSCs by whole bone marrow adherent culture technique and to establish an easy and effective method to isolate and culture BMSCs.
METHODS: The BMSCs were isolated by whole bone marrow adherent culture technique, and purified and amplified by passage. BMSCs were induced to differentiate into adipocytes, osteocytes and chondrocytes in special differentiation condition.   
RESULTS AND CONCLUTION: The purity of the BMSCs isolated by whole bone marrow adherent culture technique was more than 90%. The adherent cells displayed an abundant presence of CD73, CD90, CD105 and absence of Hematopoietic cell phenotype CD34, CD45 and HLA-DR which were detected by flow cytometry. The cell doubling time was (24.04±0.49) hours; Cell cycle showed that there was percentage of stem cells as G0 /G1 71.63% and S+G2+M 28.37% respectively. The induced and differentiated results showed than BMSCs could be differentiated into adipocytes, osteocytes and chondrocytes. Based on these findings, the whole bone marrow adherent culture technique is a better method to obtain MSCs from human bone marrow.
