| 摘 要： | 目的:检测抗VEGFR-2嵌合Fab抗体对裸鼠肝癌原位移植瘤血管生成的影响.方法:建立裸鼠肝癌H22细胞原位移植瘤模型,随机分成生理盐水组(n=12)和抗体组(n=12).采用免疫组织化学SP染色法对两组肝脏移植瘤进行血管染色,观察其微血管密度(MVD)情况.结果:成功建立裸鼠H22肝癌原位移植瘤模型,HE染色显示肝脏移植瘤为肝细胞肝癌,免疫组化结果显示肝脏实体瘤内微血管密度抗体组较生理盐水组显著性减少(25.64± 1.53 vs 8.65± 1.79,P＜0.05).结论:抗VEGFR-2嵌合Fab抗体能够抑制裸鼠肝癌原位移植瘤的血管生成. |

| Abstract: | Objective： To investigate the effect of a chimeric anti-VEGFR-2 Fab antibody on angiogenesis of an orthotopic xenograft tumor in nude mice.Methods： An orthotopic xenograft tumor model of hepatocellular carcinoma was created by injection of H22 cells directly into the liver parenchyma of nude mice,and twenty-four nude mice bearing orthotopic HCC were randomly divided into two groups： saline group（n=12）,antibody group（n=12）.The microvessel density in H22 solid tumor of the two groups was counted by SP staining of immunohistochemistry.Results： An orthotopic xenograft tumor model of hepatocellular carcinoma was successfully created and was showed as hepatocellular carcinoma by hematoxylin-eosin staining.The microvessel density in antibody group was significantly lower than that in saline group（25.64±1.53 vs 8.65±1.79,P0.05） by immunohistochemistry.Conclusions： The chimeric anti-VEGFR-2 Fab antibody can inhibit angiogenesis of an orthotopic xenograft tumor in nude mice. |
