摘要:

背景:组织工程需要大量的种子细胞,尚未见芒果苷促进骨髓间充质干细胞增殖的报道。
目的:观察芒果苷对体外培养大鼠骨髓间充质干细胞增殖作用。
方法:通过全骨髓贴壁法体外分离、培养、纯化大鼠骨髓间充质干细胞。应用MTT法检测芒果苷细胞毒性并绘制生长曲线,细胞周期检测及细胞增殖示踪检测,观察不同浓度的芒果苷对大鼠骨髓间充质干细胞毒性及生物学性状影响,不同浓度的芒果苷对体外培养骨髓间充质干细胞增殖的影响。
结果与结论:在一定浓度范围内,不同浓度的芒果苷均可促进大鼠骨髓间充质干细胞增殖、分化,并呈现出一定的量效、时效关系。药物作用时间48,72 h,芒果苷20 μmol/L、40 μmol/L组作用最为显著(P < 0.01);80 μmol/L组次之(P < 0.05)。芒果苷浓度20,40,80 μmol/L等各组细胞S期比值均较正常细胞显著增高,以芒果苷40 μmol/L组最显著(P < 0.05)。提示芒果苷具有促进体外大鼠骨髓间充质干细胞细胞增殖的作用。

Abstract:

BACKGROUND: Tissue engineering requires a lot of seed cells, and the reports on mangiferin promotion of bone mesenchymal stem cells proliferation are rare.
OBJECTIVE: To observe the effects of mangiferin on the proliferation of rat bone marrow mesenchymal stem cells in vitro.
METHODS: Bone marrow mesenchymal stem cells from rats were isolated, cultured and purified by the whole bone marrow adherence method. The MTT method was used to detect the cytotoxicity of mangiferin and the growth curve was drawn, and the cell cycle detection and the cell proliferation tracer detection were used to observe the effect of mangiferin at different concentrations on the biological characteristics of rat bone marrow mesenchymal stem cells, as well as the proliferation of bone marrow mesenchymal stem cells.
RESULTS AND CONCLUSION: In a certain range of concentration, different concentrations of mangiferin could promote the proliferation and differentiation of bone marrow mesenchymal stem cells, and showed a dose and time dependent manner. The mangiferin at the concentration of 20 μmol/L and 40 μmol/L had the most significant effect (P < 0.01); followed by the concentration of 80 μmol/L induction for 48 and 72 hours (P < 0.05). The S phase ratio of the cells induced with 20, 40 and 80 μmol/L mangiferin was higher than that of the normal cells, and the S phase ratio of the bone marrow mesenchymal stem cells induced with 40 μmol/L mangiferin was the highest (P < 0.05). Mangiferin capromote the proliferation of bone marrow mesenchymal stem cells in vitro.Li XF, Zhao JM, Luo SX, Cheng JW, Liu JT.
