摘要
人类结直肠癌 (CRC) 患者衍生的类器官 (PDO) 是一个强大的离体平台,可直接评估分子改变和治疗对肿瘤细胞增殖、分化、对化疗的反应、肿瘤-微环境相互作用以及 CRC 其他方面的影响生物学。新一代测序研究表明,CRC 是一种具有多种不同亚型的高度异质性疾病。 PDO 是研究 CRC 的一种有前途的新工具,因为它们能够准确地概括其源肿瘤并因此再现这种异质性。本综述总结了 CRC PDO 在癌症干细胞 (CSC) 和癌症干细胞生态位研究中的最新进展。重点领域包括 PDO 与了解 CSC 相关旁分泌信号传导的相关性,识别 CSC 与肿瘤微环境之间的相互作用,以及模拟 CSC 驱动的对化疗和靶向治疗的耐药性。最后,我们总结了有关使用 PDO 识别和验证 CSC 目标及其在个性化医疗中的潜在用途的当前发现。
