Abstract

背景与目的肺癌是严重威胁人类生存和发展的恶性疾病之一,本研究旨在建立人肺腺癌细胞系,探讨其生物学特性,为进一步明确肺癌的发生机理,提供一个技术平台。方法取人肺腺癌新鲜手术肿瘤标本,经组织块体外培养并克隆建系,命名为Ch-Huang-1。采用光镜、细胞生长曲线、染色体核型分析、克隆形成率及免疫缺陷小鼠成瘤实验对细胞系生物学特性进行分析。结果细胞系及移植瘤标本证实具有腺癌恶性细胞特征。生长曲线呈S型,细胞群体倍增时间为36 h。分裂指数曲线为倒V字型,培养第30小时处于分裂期的细胞最多。克隆形成率为0.803%±0.078%。观察到肿瘤细胞染色体数目为亚三倍体,有明显的染色体异常。裸鼠皮下异种移植形成移植瘤。结论根据细胞系特征显示该细胞系是一新建的肺腺癌细胞系。
