摘要 目的探讨食管癌组织中干细胞Nanog蛋白表达,分析其与食管癌临床病理特征的关系。方法收集87例食管癌患者的癌组织及癌旁正常组织标本,采用免疫组化法检测癌组织及癌旁正常组织中的Nanog蛋白表达,同时用免疫荧光技术检测食管癌细胞系TE-1、Eca-109中的Nanog蛋白表达。结果 Nanog蛋白在食管癌组织中的表达水平高于癌旁正常组织(P<0.05),Nanog蛋白在食管癌组织中的表达与其病理分期、分化程度和淋巴结转移有关(P均<0.05)。食管癌细胞系TE-1、Eca-109中的Nanog阳性蛋白呈高表达,且表达存在异质性;多数细胞以细胞质表达为主,少数以细胞核表达为主,细胞核表达阳性率为10%。结论 Nanog蛋白在食管癌组织中的表达与食管癌的发生、发展及转移密切相关。
