Organoids are 3D organ-like structures grown from stem cells in vitro that mimic the organ or disease from which they are derived. Due to their stem cell origin, organoids contain a heterogeneous population of cells reflecting the diversity of cell types seen in vivo. Similarly, tumour organoids reflect intratumoural heterogeneity in a way that traditional 2D cell culture and cell lines do not, and, therefore, they show greater promise as a more relevant model for effective disease modelling and drug testing. Tumour organoids arise from cancer stem cells, which contribute to many of the greatest challenges to cancer treatment, including therapy resistance, tumour recurrence, and metastasis. In this review, we outline methods for generating colon organoids from patient-derived normal and tumour tissues. Furthermore, we discuss organoid biobanking, applications of organoids in disease modelling, and a range of platforms applicable to high-throughput drug testing, including apical-out/reverse-polarity colon organoids. |
