1、沙利度胺對于M7細(xì)胞作用的實(shí)驗(yàn)研宄馮林瀘州醫(yī)學(xué)院附屬醫(yī)院血液科四川瀘州646000【摘要】目的:研究沙利度胺對于M7細(xì)胞(巨核細(xì)胞白血病細(xì)胞)的作用。方法:用Sigma公司生產(chǎn)的沙利度胺原料藥。以0.1%DMSO(二甲基亞砜)為陰性對照組,以M7細(xì)胞為空白組,以不同濃度的沙利度胺作用于M7細(xì)胞,用CCK-8方法(細(xì)胞計(jì)數(shù)試劑盒方法)觀察不同濃度不同時(shí)間沙利度胺對于M7細(xì)胞的增值抑制作用;以不同濃度沙利度胺分別作用M7細(xì)胞24h,48h,72h后,用ELISA方法檢測上清液中VEGF(血管內(nèi)皮生長因子)的濃度;以不同濃度沙利度胺分別作用M7細(xì)胞24h,48h,72h后,經(jīng)HE及DAP
2、I(二脒基苯基吲哚)染色后,用光學(xué)顯微鏡及熒光顯微鏡觀察M7細(xì)胞形態(tài)變化,并應(yīng)用統(tǒng)計(jì)學(xué)分析實(shí)驗(yàn)結(jié)果。結(jié)果:沙利度胺可明顯抑制M7細(xì)胞分泌VEGF,并且抑制作用隨著沙利度胺濃度及作用時(shí)間而增強(qiáng);在CCK-8實(shí)驗(yàn)中,各組M7細(xì)胞與空白組相比,發(fā)現(xiàn)沙利度胺對M7細(xì)胞無明顯抑制作用;光學(xué)顯微鏡觀察不同時(shí)間段不同組,各組M7細(xì)胞與空白組相比較,細(xì)胞生長較好,呈圓形,細(xì)胞核大,核膜清晰。熒光顯微鏡下,未見明顯凋亡小體。結(jié)論:1.沙利度胺能夠明顯抑制M7細(xì)胞分泌VEGF,并且呈時(shí)間濃度依賴性。2.沙利度胺對于M7細(xì)胞沒有明顯抗增殖效應(yīng)及誘導(dǎo)其凋亡的作用?!娟P(guān)鍵詞】沙利度胺;VEGF;M7細(xì)胞;凋
