Summary: We present a protocol to generate organoids from air-liquid-interface (ALI)-differentiated nasal epithelia. We detail their application as cystic fibrosis (CF) disease model in the cystic fibrosis transmembrane conductance regulator (CFTR)-dependent forskolin-induced swelling (FIS) assay. We describe steps for isolation, expansion and cryostorage of nasal brushing-derived basal progenitor cells, and their differentiation in ALI cultures. Furthermore, we detail the conversion of differentiated epithelial fragments into organoids of healthy controls and CF subjects for validating CFTR function and modulator responses.For complete details on the use and execution of this protocol, please refer to Amatngalim et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
