Abstract: 目的:肝脏内存在有两种纤维母细胞,用免疫组化方法对这两种细胞群在肝纤维化(hepatic fibrosis HF)中活化后的细胞形态进行组织学鉴别.方法:Wistar系雄性鼠用于实验动物模型制作:胆总管结扎(bile duct ligation BDL)诱导肝纤维化动物模型,用SABC法来检测.一次抗体为glial fibrillary acidic protein (GFAP)和 Vinculin.结果:CCl4腹腔注射后48h中央静脉周围的星形细胞在GFAP和Vinculin染色呈强阳性;另外,BDL 96h后门脉区纤维母细胞在Vinculin染色中显示阳性,而在GFAP,染色中未发现有变化.结论:Vinculin在肝星形细胞和门脉区域的纤维母细胞有相同的阳性结果,GFAP被证明能够用于区别有活性的肝星形细胞和门脉区域的纤维母细胞.
