Cilia are antenna-like organelles associated with a spectrum of human disease states. The functions of cilia remain incompletely understood, particularly in humans where cellular models do not recapitulate complex disease. Here we show that human pluripotent stem cells lacking the kinesin-2 subunits KIF3A or KIF3B, generated by CRISPR gene editing, establish a general tool for the study of ciliary function in tissue morphogenesis. Both KIF3A−/− and KIF3B−/− hPSCs lack cilia, yet remain self-renewing and pluripotent, enabling efficient derivation of diverse somatic cells. Derived tissues and organoids express multi-lineage phenotypes modeling the ciliopathy spectrum, including neuronal and nephron differentiation defects, and polycystic kidney disease. Modular culture conditions and biochemical analysis reveal that human cilia mediate a critical switch in hedgehog signaling during organoid differentiation, and constitutively release extracellular vesicles containing signaling molecules associated with these phenotypes. KIF3A−/− and KIF3B−/− hPSCs thus establish a human genetic system linking complex ciliary phenotypes with endogenous mechanisms, for therapeutics discovery and regenerative applications.
