摘要: 目的 探讨单克隆形态结合SEMA3B检测分离胃癌中的致瘤成分。方法 采用克隆的形态并分类,计算克隆形成率;采用Western blot法检测不同克隆细胞中SEMA3B的表达,并观察各组克隆细胞的体内成瘤能力。结果 SGC-7901细胞可形成3种克隆形态,分为Holoclone型、Paraclone型和Meroclone型,总克隆形成率为(10.20±1.07)%;Western blot法检测发现SEMA3B在Holoclone型中表达最强,并且Holoclone型克隆细胞具有很强的体内成瘤能力。结论 本研究为探寻SEMA3B在胃癌中成瘤和增殖的作用提供了理论依据。

Abstract: Objective To investgate the morphological monoclonal combined with SEMA3B for detection of the tumorigenic components in gastric cancer.Methods Clones derived from gastric cancer SGC-7901 cells were assessed by morphological observation,the clone formation rate was calculated.The expression of SEMA3B was detected by Western blot,and the tumorigenic ability of each group was determined.Results Clones derived from GC SGC-7901 cells had three types,the total clone formation rate was(10.20±1.07)%,the expression of SEMA3B was the strongest in the Holoclone colonies,SGC-7901 cells of Holoclone clones possessed strong ability of self-renewal and in vivo tumorigenicity in the nude mice.Conclusion This study provides the experimental basis for exploring the effect of SEMA3B in gastric carcinoma tumor formation and proliferation.
