Generation of Human Nasal Epithelial Cell Spheroids for Individualized Cystic Fibrosis Transmembrane Conductance Regulator Study

Here we describe a method to generate three-dimensional spheroid cultures of human nasal epithelial cells. Spheroids are then stimulated to drive Cystic Fibrosis Transmembrane Conductance Regulator (CFTR)-dependent ion and fluid secretion, quantifying the change in the spheroid luminal size as a proxy for CFTR function.
