Establishment of Patient-Derived Organoids from Colorectal Cancer Resection Samples

Colorectal cancer (CRC) organoids can serve as powerful preclinical cell models that accurately reflect individual tumor characteristics. Establishing a patient-derived CRC biobank facilitates a wide range of applications, including basic oncology research, new drug discovery, drug testing, and personalized medicine. This chapter details the process of generation of organoids from surgical samples of primary and metastatic CRC as well as from tumor adjacent normal colon tissues. Furthermore, best practices for cultivation and cryostorage of CRC organoids are described.
