骨髓基质细胞:
是存在于骨髓内,有不定向多方向分化潜能的一类干细胞,具有分化成骨细胞、软骨细胞、心肌细胞、骨骼肌细胞和脂肪细胞等细胞的潜能,目前常用于细胞实验中。
甲萘醌7:是维生素K2最广泛、最强大的活性成分,有抗骨质疏松等作用,但在关于其在体外对骨髓基质细胞的诱导作用尚未见报道。

 

摘要
背景:
目前甲萘醌7的研究主要集中在其抗骨质疏松的作用方面,关于其对体外细胞培养体系中大鼠骨髓基质细胞的作用尚不明确。
目的:观察甲萘醌7对大鼠骨髓基质细胞增殖及分化的影响。
方法:提取大鼠骨髓基质细胞,体外培养扩增后,种植骨髓基质细胞于细胞培养皿中,分别用质量浓度10-6,10-5,10-4 g/L的甲萘醌7及100 μg/L 的碱性成纤维细胞生长因子诱导骨髓基质细胞增殖,检测不同组骨髓基质细胞的相应吸光度值。于第2,4,6和8天检测骨髓基质细胞碱性磷酸酶水平和钙结节数量,并检测骨钙素、骨桥蛋白和Runx2蛋白的mRNA表达情况。
结果与结论:①细胞增殖:甲萘醌7诱导的骨髓基质细胞增殖良好,各浓度的甲萘醌7及碱性成纤维细胞生长因子组均有促进骨髓基质细胞增殖的作用(P < 0.05);②相关蛋白mRNA表达:甲萘醌7组比对照组能表达更多的碱性磷酸酶和钙结节。质量浓度10-4 g/L的甲萘醌7能上调骨钙素、骨桥蛋白和Runx2蛋白mRNA的表达(P < 0.05);③结果证实,甲萘醌7能诱导骨髓基质细胞向成骨方向分化,可用于骨组织工程中种子细胞的诱导剂。

Abstract:

BACKGROUND: The current research on menadione 7 mainly focuses on its anti-osteoporosis effect, and its role in rat bone marrow stromal cells in vitro culture system is unclear.
OBJECTIVE: To investigate the effect of menadione-7 on the proliferation and differentiation of Bone marrow stromal cells, and to provide theoretical basis for the application of menadione-7 in bone tissue engineering.
METHODS: Bone marrow stromal cells were obtained from rats by surgery. After cultured in vitro, bone marrow stromal cells were incubated in cell culture dishes. The proliferation of bone marrow stromal cells was induced by 10-6, 10-5 and 10-4 g/L menadione-7 and 100 μg/L basic fibroblast growth factor (bFGF). The corresponding absorbance value of bone marrow stromal cells was detected in each group. The levels of alkaline phosphatase and the number of calcium nodules in bone marrow stromal cells were detected at 2, 4, 6 and 8 days, and the mRNA expression of osteocalcin, osteopontin and Runx2 was detected at 4, 6 and 8 days.
RESULTS AND CONCLUSION: Bone marrow stromal cells induced by menadione-7 proliferated well, and the cell proliferation could be promoted by different concentrations of menadione-7 and bFGF (P < 0.05). More alkaline phosphatase and calcium nodules were expressed in menadione-7 groups than the control group. The mRNA expression of osteocalcin, osteopontin and Runx2 could be significantly up-regulated by 10-4 g/L menadione-7 (P < 0.05). To conclude, bone marrow stromal cells can be induced by menadione-7 into osteogenic differentiation and menadione-7 can be used as an inducer for seed cells in bone tissue engineering.
