2、24h、48h、72h后,MTT法檢測(cè)大鼠成骨細(xì)胞的增殖情況;用對(duì)硝基苯二鈉基質(zhì)動(dòng)力學(xué)法(PNPP)測(cè)定細(xì)胞內(nèi)堿性磷酸酶(ALP)的活性;培養(yǎng)48h后用RT-PCR方法檢測(cè)Ⅰ型膠原(COL-Ⅰ)mRNA的表達(dá)。結(jié)果5%和10%菟絲子含藥血清在48h和72h能顯著促進(jìn)成骨細(xì)胞增殖并提高ALP活性;在48h時(shí)10%菟絲子含藥血清可促進(jìn)COL-ⅠmRNA的表達(dá)。結(jié)論10%菟絲子含藥血清能夠明顯促進(jìn)大鼠成骨細(xì)胞的增殖與分化,表明其具有促進(jìn)成骨作用。[關(guān)鍵詞]菟絲子;含藥血清;成骨細(xì)胞;增殖;分化EffectofDodder-ContainingSerumontheMetabolismofOs
