摘要:

背景:在组织工程领域,关于骨髓间充质干细胞定向诱导分化的研究越来越多,但是细胞培养基中不同成分会对骨髓间充质干细胞的体外增殖分化产生影响。
目的:针对培养基中不同因子对骨髓间充质干细胞定向诱导分化的作用加以综述。
方法:第一作者应用计算机检索1998年1月至2012年4月Pubmed数据库及万方数据库。检索英文关键词为“bone marrow mesenchymal stromal cells, cell culture medium, differentiation”,中文关键词为“骨髓间充质干细胞,细胞培养,定向诱导分化”,纳入有关不同因子对骨髓间充质干细胞向成骨细胞、软骨细胞和脂肪细胞定向诱导分化作用的文献,排除重复研究。
结果与结论:计算机初检共得到184篇文献,根据纳入排除标准,对其中30篇文献进行综述。大体说来,骨髓间充质干细胞向成骨分化的主要因子有地塞米松、转化生长因子、维生素C、维生素D3、β-甘油磷酸钠及乙烯雌酚等;向软骨分化的主要因子有地塞米松、转化生长因子、维生素C、胰岛素样生长因子及成纤维细胞生长因子等;向脂肪细胞转化的主要因子有地塞米松、3-异丁基-1-甲基黄嘌呤、胰岛素和消炎痛等,但是其中一些因子的作用机制及不良反应还不明确,需要进一步的研究与验证。同时,骨髓间充质干细胞在骨髓中的含量较低,不同的分离方法会导致不同的分离率,因此如何选取一种分离率高的分离方法仍有待研究。

Abstract:

BACKGROUND: In the field of tissue engineering, there are an increasing number of studies describing oriented differentiation of bone marrow mesenchymal stem cells. Different ingredients of culture medium produce effects on in vitro proliferation and differentiation of bone marrow mesenchymal stem cells.
OBJECTIVE: To summarize the effects of different ingredients of cell culture medium on oriented differentiation of bone marrow mesenchymal stem cells.
METHODS: A computer-based online retrieval of PubMed and Wanfang databases was performed to search papers published between January 1998 and April 2012 using the key words “bone marrow mesenchymal stem cells, cell culture medium, differentiation” in English and Chinese, respectively. Papers regarding effects of different ingredients of culture medium on osteogenic, chondrogenic and adipogenic differentiation of bone marrow mesenchymal stem cells were collected. Papers with repetitive contents were excluded.
RESULTS AND CONCLUSION: A total of 184 papers were initially retrieved. According to inclusion and exclusion criteria, 30 of them were suitable for final analysis. Generally speaking, dexamethasone, transforming growth factor, vitamin C, vitamin D3, β-sodium glycerophosphate, and diethylstilbestrol are the main ingredients of cell culture medium to induce osteogenic differentiation of bone marrow mesenchymal stem cells; dexamethasone, transforming growth factor, vitamin C, insulin-like growth factor and fibroblast growth factor are the main ingredients of cell culture medium to induce chondrogenic differentiation of bone marrow mesenchymal stem cells; dexamethasone, 3-isobutyl-1-methylxanthine, insulin and indometacin are the main ingredients of cell culture medium to induce adipogenic differentiation of bone marrow mesenchymal stem cells. Nevertheless, the mechanisms of action and adverse events of some ingredients are poorly understood and need further investigation. In addition, bone marrow mesenchymal stem cells are at low level in the bone marrow and different isolation methods will lead to different cell proportions. Therefore, a method of isolating high proportion of cells should be developed.
