Human pluripotent stem cells (hPSCs) have dual value as microphysiological laboratory models and regenerative therapeutics. hPSCs are epithelial cells, but the extent to which hPSCs and descendant epithelia can reconstitute lineage-specific functions remains poorly understood. Here the Inventors show that hPSCs in three-dimensional cultures and their differentiated descendants can functionally recapitulate tissue-specific epithelial morphogenesis, physiology, and disease.
