In the past decade, the discovery of genome editing tools and 3D culture techniques has revolutionized the field of biology. CRISPR-Cas9 and organoid culture have provided important tools to uncover organ development and model cancer, with genetically modified organoids successfully recapitulating the neoplastic events of human tumors in animal models.
Two breakthrough techniques that have totally revolutionized biology in last 1 decade are the discovery of genome editing tools and growing the stem cells/primary tissue explants in defined 3D culture. In this regard the discovery of CRISPR-Cas9 as a specific gene editing tool and organoid culture from adult stem cell has provided easy handy tools to uncover the process of organ development and also modeling cancer. Genetically modified organoids have been developed by sequential knockout and knockin of driver mutations by genome editing followed by niche-based selection. The modified organoids when xenotransplanted in animal models faithfully recapitulate the neoplastic events of human tumors. The present review focuses on the merging of these two powerful technologies in understanding the complexities of colon and liver cancer.
