The power of organoids in speeding up lifesaving drug development

Organoids are miniature tissue or organ models formed by stem cells (including pluripotent stem cells, tissue-specific adult stem cells, etc.) or progenitor cells in an in vitro three-dimensional culture system, which possess structural features and partial functions analogous to their corresponding in vivo organs. In 2009, the Hans Clevers laboratory developed the first intestinal organoid, marking the inception of organoid-based disease modeling.
