Abstract

Organoids are 3D organotypic cultures derived from tissue stem cells, embryonic cells and induced pluripotent stem cells (iPSCs), that mimic the structure and function of organs ranging from the colon1 to the brain2. They are amenable to essentially all cell biological and molecular technologies that are commonly used for cell lines, including genome editing with CRISPR-Cas technology3. Organoids are proving to be an enabling tool for applications ranging from fundamental biology to personalized or regenerative medicine (Method of Year 2017, Nat. Methods). Organoids grown from adult stem cells (obtained from tissue biopsies of almost any organ and animal species) provide a potentially powerful research platform e.g. for ex vivo phenotyping in livestock breeding programs4 and investigating genotype-to-phenotype relationships. Organoids derived from pluripotent stem cells are increasingly used in human biology and for designing new therapies; they provide controlled genetic backgrounds and the ability to drive their differentiation into virtually any cell type.

This talk will provide an overview of organoids and their employment in fundamental and applied research, with examples emerging in livestock.
