摘要
背景:研究表明,蛇床子素可以通过促进成骨细胞分化而促进骨形成,但是蛇床子素抗骨质疏松效应的机制尚不明确。目的:观察蛇床子素对体外培养大鼠成骨细胞增殖与分化的影响,探究其抗骨质疏松效应的机制。方法:采用二次酶消化法分离大鼠成骨细胞,并使用碱性磷酸酶染色以及矿化结节染色进行鉴定。实验分5组,分别为溶剂对照组、β-雌二醇组以及蛇床子素低、中、高剂量组(1×10-6,1×10-5,1×10-4 mol/L)。用CCK-8法检测各组细胞增殖情况,通过检测各组细胞内碱性磷酸酶活力以及矿化结节染色评价细胞分化情况,蛋白免疫印迹法检测GRP78、PDI、CHOP蛋白表达。结果与结论:(1)1×10-4,1×10-5 mol/L蛇床子素可抑制成骨细胞增殖;(2)10-4 mol/L蛇床子素可增加成骨细胞碱性磷酸酶活力、增强成骨细胞矿化能力;(3)10-4mol/L蛇床子素可降低GRP78蛋白水平,增加PDI及CHOP蛋白表达;(4)结果表明,蛇床子素可促进成骨细胞分化,可能通过内质网应激抑制成骨细胞增殖。
