Highly-parallel production of designer organoids by mosaic patterning of progenitors

Abstract

AbstractHuman organoids are a promising approach for disease modeling and regenerative medicine. However, organoid variability and limited control over morphological outcomes remain significant challenges. Here we extend a DNA ‘velcro’ cell patterning approach, precisely controlling the number and ratio of human stem cell-derived progenitors contributing to nephron and mosaic nephron/ureteric bud organoids within arrays of microwells. We demonstrate long-term control over organoid size and morphology, decoupled from geometric constraints.
