细胞粘附分子在肿瘤细胞侵袭和转移中的作用已越来越为人们重视,研究表明,上皮钙粘附蛋白(epithelialcadherin,E CD)和白细胞分化抗原CD4 4分子拼接变异体(CD4 4v6 )的表达与肿瘤的浸润、转移有密切关系。我们采用免疫组织化学方法研究E CD和CD4 4v6的表达在肝外胆管癌发生、发
The role of cell adhesion molecules in tumor cell invasion and metastasis has attracted more and more attention. Studies have shown that epithelial cadherin (E CD) and interleukin-4 (CD4 4v6) Expression and tumor invasion, metastasis are closely related. We used immunohistochemical methods to study the expression of ECD and CD4 4v6 in extrahepatic cholangiocarcinoma, hair
