摘要 目的观察转染pc DNA3.1-HBV Creg DNA质粒的小鼠肝细胞表面干性分子CD44、CD90、CD133的表达变化。方法从含有pc DNA3.1-HBV Creg DNA质粒的Ecoli DH5α菌株中提取pc DNA3.1-HBV Creg DNA质粒。取SPF级正常小鼠的肝细胞,常规培养,待细胞贴壁后,加入50μL pc DNA3.1-HBV Creg DNA混合转染细胞。采用免疫细胞化学染色法检测转染前后小鼠肝细胞表面干性分子CD44、CD90、CD133表达。结果转染前,部分小鼠肝细胞CD90、CD133呈阳性,且阳性染色细胞都是圆形。未见有CD44阳性染色细胞。转染pc DNA3.1-HBV Creg DNA后,小鼠肝细胞表面干性分子CD44、CD90、CD133呈阳性染色。结论转染pc DNA3.1-HBV Creg DNA质粒的小鼠肝细胞表达CD44、CD90、CD133。HBV Creg DNA可能影响小鼠肝细胞表面干性分子CD44的表达。
