A549人类非小细胞肺癌细胞系,在1972年由科学家将一个58岁白人男性的外植体肿瘤转移并培养而成的[1]。有研究指出侧群细胞亚群约占A549细胞总数的5.93%[2]。在组织发现的A549细胞呈鳞状,负责电解质等物质在整个肺泡中的扩散,又可以通过胞磷胆碱途径合成含有高度不饱和脂肪酸卵磷脂

A549细胞

科研用途

A549细胞具有快速的增生速度可归因于环氧合酶2的大量表达。如果将A549细胞进行体外培养,就会生长为附着或紧贴在培养基上的单层细胞[1]。当生长足够长的时间时,A549细胞会进行细胞分化。A549细胞目前被应用作研究肺癌和开发针对其的药物疗法的模型[3]。A549细胞已成为II型肺泡上皮细胞的模型,并且在研究肺组织的代谢过程及将药物输送到组织的可能机制中具有实用性[4]。同时这些细胞已分别通过细胞培养和异种移植,在体外和体内作为紫杉醇欧洲紫杉醇和贝伐单抗的试验地方,以开发新的肺癌药物。

对A549细胞的深入研究已能阐明细胞谱系树 (pedigree-tree) 的概况,并且证明姐妹细胞 (sister cells) 之间的行为相关性[5]。这种观察可以作为一种测量工具,确定细胞应激及遗传是对药物治疗的反应[6]。A549细胞也可应用于病毒研究和相关的蛋白质表达变化[7]。尽管A549细胞是癌细胞系,但是科研人员也会研究它对结核病的反应,特别是趋化因子的产生,因为它是由入侵细菌诱导的[8]
