Platform: iPSC-derived airway plated on 2D-air liquid interface through basal cell intermediate. Purpose of experiment: To examine the role of mutant CFTR on IPSC-derived airway epithelium (ie. immune dysregulation; dysregulated calcium channel signaling etc). Description of samples:Typical phenotype CF F508del (1565) and syngeneic CFTR-corrected (1564) iPSCs- derived airway epithelium at D90 (D15 CD47hi/CD26lo; replated in 3DMG cultured in 210DCIY x 2 weeks, single-cell passaged and cultured in PNExPlus+dual smad media in 3D, s/p 2 NGFR sorts, cultured at air-liquid interface at 2D) Overall design: iPSCs- derived airway epithelium from CF and CFTR-corrected syngeneic line, at D90 (D15 CD47hi/CD26lo; replated in 3DMG cultured in 210DCIY x 2 weeks, single-cell passaged and cultured in PNExPlus+dual smad media in 3D, s/p 2 NGFR sorts, cultured at air-liquid interface at 2D)
