Determining Ciliary Function and Membrane Impermeability of the Pseudostratified Lung Airway Epithelium

Air-liquid interface culture is commonly used to develop pseudostratified airway epithelium by differentiating primary normal human bronchial epithelial cells that mimic the apical side of the lung airway. Here, we describe an easy protocol for determining its quality by monitoring its biophysical properties, such as ciliary function and membrane integrity.
