摘要 目的观察胰岛素样生长因子-1(IGF-1)对体外培养的小鼠前成骨样MC3T3-E1细胞增殖及I型胶原蛋白合成的影响,探讨IGF-1对骨代谢可能的影响机制。方法不同浓度rhIGF-1刺激体外培养的MC3T3-E1,用噻唑蓝(MTT)法测定细胞增殖能力。结果一定浓度IGF-1能明显增加成骨细胞数量(P<0.05),在1 ng/mL~100 ng/mL这种作用与IGF-1的浓度呈正相关;经rhIGF-1的刺激,成骨细胞I型胶原蛋白的表达明显高于对照组(P<0.05);半定量RT-PCR显示在rhIGF-1干预48h后,I型胶原蛋白mRNA表达较对照组明显增加。结论IGF-1对MC3T3-E1细胞有明显的促增殖作用,在0.1 ng/mL~100 ng/mL之间呈浓度依赖性,IGF-1能促进成骨细胞I型胶原蛋白的合成及其mRNA的表达。
