摘要 肺癌干细胞(lung cancer stem cell,LCSC)是肺癌组织中一小群具有自我更新及分化潜能,并且具有耐药性的特殊细胞。LCSC是目前肺癌研究中的热点。研究者通过对肺癌中CD133阳性细胞侧群(side population,SP)细胞及耐药存活细胞(drug surviving cell,DSC)的研究,证实了LCSC的存在;而乙醛脱氢酶1(aldehyde dehydrogenase 1,ALDH1)、八聚体结合转录因子-4(octamer-binding transcription factor 4,Oct-4)及CD44可能是鉴定LCSC的新标志物。Notch、Wnt及Hedgehog信号通路与LCSC的发生及维持关系密切,靶向阻断这些信号通路可以减少肺癌组织中LCSC的比例,可能成为肺癌靶向治疗的新策略。
