J Appl Oral Sci:康力龙可促进成骨细胞的成骨分化

2019-02-17 不详 网络

康力龙(ST)是一种具有高合成代谢潜力的合成雄激素。虽然已知雄激素在骨代谢中起积极作用,但是对骨细胞的ST作用尚未充分阐明以支持其在骨增强程序中的临床应用。本研究旨在评估ST对SaOS-2细胞成骨活性和基因表达的影响。在6,12和24天通过茜素红S和钙黄绿素染色技术评估响应增加的ST剂量(0-1000nM)的矿化基质的SaOS-2沉积。通过RT-PCR分析runt相关转录因子2(RUNX2),维生

康力龙(ST)是一种具有高合成代谢潜力的合成雄激素。虽然已知雄激素在骨代谢中起积极作用,但是对骨细胞的ST作用尚未充分阐明以支持其在骨增强程序中的临床应用。本研究旨在评估ST对SaOS-2细胞成骨活性和基因表达的影响。

在6,12和24天通过茜素红S和钙黄绿素染色技术评估响应增加的ST剂量(0-1000nM)的矿化基质的SaOS-2沉积。通过RT-PCR分析runt相关转录因子2(RUNX2),维生素D受体(VDR),骨桥蛋白(SPP1)和骨粘连蛋白(ON)的基因表达。

结果显示,ST显著影响SaOS-2成骨活性:染色显示存在圆形钙化结节,其数量和大小随时间增加并且取决于ST剂量。 RT-PCR突出了与成骨分化相关的基因的ST调节。

总之,该研究提供了令人鼓舞的结果,显示ST促进了SaOS-2细胞的成骨分化。需要进一步的研究来验证原代成骨细胞中的这些数据并研究ST分子作用通路。
