中文摘要：

目的：研究人肝癌细胞株 Bel -7402鸡胚尿囊膜移植瘤模型建立的方法，观察和分析其血管生成的特征。方法：将不同浓度的人肝癌细胞株 Bel -7402接种于鸡胚尿囊膜（ chick embryo chorioallantoic mem-brane，CAM），观察影响肝癌鸡胚尿囊膜移植瘤模型瘤体成活的因素、瘤体生长特征和血管生成情况。结果：建立了人肝癌细胞 CAM 移植瘤模型。移植瘤模型瘤体易于生长，具有较强的血管生成作用。结论：该移植瘤模型易于复制，能动态观察肝癌的血管生成过程，可用于肝癌的生物学行为、药物筛选等领域的研究。

英文摘要：

Objective：To establish a human liver cancer model on the chick embryo chorioallantoic membrane （CAM）and study its characteristics of angiogenesis. Methods：Human liver cancer cell line Bel - 7402 at different concentrations were inoculated on the CAM. To observe the factors affecting the survival of the transplanted human liv-er cancer,growth characteristics of the transplanting tumor and the characteristics of angiogenesis. Results：The trans-plantation tumor modeI of human liver cancer in CAM was successfully established. It was found that transplantation tumor was easy to grow and it showed strong angiogenesis effects. Conclusion：It is feasible to establish a transplanta-tion tumor model of human liver cancer on CAM. The model can be easily duplicated,which provides a useful animal model for studying the angiogenesis and biological properties of colorectal cancer and can be used in the research of the drug selection for human liver cancer.
