巴戟天对大鼠骨髓基质细胞增殖、成骨分化及Cbfα1基因表达的影响

巴戟天对大鼠骨髓基质细胞增殖、成骨分化及Cbfα1基因表达的影响摘要：巴戟天是一种中草药，广泛应用于中医药领域，其成分复杂，是一种植物多酚类化合物，与骨骼生长发育具有密切关系。本研究旨在探究巴戟天对大鼠骨髓基质细胞增殖、成骨分化及Cbfα1基因表达的影响。实验分为对照组、低浓度组和高浓度组，以大鼠骨髓基质细胞为实验对象，采用MTT比色法、碱性磷酸酶染色和AlizarinRed染色法进行细胞活力、成骨分化及成骨小结节形成的检测，采用RT-PCR技术检测Cbfα1基因的表达。结果表明，巴戟天对大鼠骨髓基质细胞有促进作用，在低浓度时可以促进细胞的增殖和成骨分化，同时上调Cbfα1基因的表达，有助于细胞成骨小结节的形成。
