1、中华实验外科杂志2013年10月第3O卷第10期ChinJExpSurg,October2013,Vo1.30,No.10·2067··肝脏外科·小鼠原位肝癌移植模型中髓系来源抑制性细胞的表达赵文秀张正奇许雅苹尹震宇王效民【摘要】目的观察小鼠原位肝癌移植模型中髓系来源抑制性细胞(MDSCs)的表达。方法将10只BALB/c小鼠随机分为两组:正常组和荷瘤组,后组是将H22肝癌细胞注射到肝左外叶,制作小鼠原位肝癌移植模型。10d后处死小鼠。流式细胞术检测两组小鼠外周血、骨髓、脾脏及肝脏组织中MDSCs的表达。结
2、果荷瘤组小鼠外周血、骨髓和脾脏中的MDSCs比例为[(47.73±6.0o)、(71.90±4.30)、(11.21±1.19)%],均明显高于正常组小鼠[(18.33±2.31)、(59.03±4.5O)、(5.82±0.58)%];正常小鼠肝组织中MDSCs占肝内白细胞6.5%,荷瘤小鼠肝癌组织、癌旁组织中MDSCs占肝内白细胞分别为43.8%和12.8%。结论在小鼠原位肝癌移植模型中,MDSCs表达明显上调,为研究MDSCs在肝癌发生发展中的作用提供了良好的动物模型。【关键词】癌,肝细胞;原位移植;模
