Organoids can enable the study of solid tumors initiated from a single cancer stem cell (CSC) vivo. We describe a serial tumor organoid plating protocol using primary colorectal cancer (CRC) tissues as a rapid and cost-efficient approach to evaluate the impact of therapeutic interventions on CSC functions. We detail the isolation of primary colorectal CSCs, organoid embedding, serial passaging, and CSC-related analytical techniques. For complete details on the use and execution of this protocol, please refer to Masibag et al. (2021) and Bergin et al. (2021).
类器官能够使研究从单个癌症干细胞(CSC)体内起始的实体瘤成为可能。我们描述了一种使用原发性结直肠癌(CRC)组织的连续肿瘤类器官种植方案,这是一种快速且具有成本效益的方法,可用于评估治疗干预对 CSC 功能的影响。我们详细介绍了原发性结直肠 CSC 的分离、类器官包埋、连续传代和与 CSC 相关的分析技术。如需详细了解本协议的使用和执行,请参阅 Masibag 等人(2021 年)和 Bergin 等人(2021 年)。
