巴戟天對大鼠骨髓基質(zhì)細(xì)胞增殖、成骨分化及Cbfα1基因表達(dá)的影響

巴戟天對大鼠骨髓基質(zhì)細(xì)胞增殖、成骨分化及Cbfα1基因表達(dá)的影響摘要：巴戟天是一種中草藥，廣泛應(yīng)用于中醫(yī)藥領(lǐng)域，其成分復(fù)雜，是一種植物多酚類化合物，與骨骼生長發(fā)育具有密切關(guān)系。本研究旨在探究巴戟天對大鼠骨髓基質(zhì)細(xì)胞增殖、成骨分化及Cbfα1基因表達(dá)的影響。實(shí)驗(yàn)分為對照組、低濃度組和高濃度組，以大鼠骨髓基質(zhì)細(xì)胞為實(shí)驗(yàn)對象，采用MTT比色法、堿性磷酸酶染色和AlizarinRed染色法進(jìn)行細(xì)胞活力、成骨分化及成骨小結(jié)節(jié)形成的檢測，采用RT-PCR技術(shù)檢測Cbfα1基因的表達(dá)。結(jié)果表明，巴戟天對大鼠骨髓基質(zhì)細(xì)胞有促進(jìn)作用，在低濃度時(shí)可以促進(jìn)細(xì)胞的增殖和成骨分化，同時(shí)上調(diào)Cbfα1基因的表達(dá)，有助于細(xì)胞成骨小結(jié)節(jié)的形成。
