Prolonged airway explant culture enables study of health, disease, and viral pathogenesis.

ABSTRACT: In vitro models play a major role in studying airway physiology and disease. However, the native lung's complex tissue architecture and nonepithelial cell lineages are not preserved in these models. Ex vivo tissue models could overcome in vitro limitations, but methods for long-term maintenance of ex vivo tissue have not been established. Here, we describe methods to culture human large airway explants, small airway explants, and precision-cut lung slices for at least 14 days. Human airway explants recapitulate genotype-specific electrophysiology; characteristic epithelial, endothelial, stromal, and immune cell populations; and model viral infection after 14 days in culture. These methods also maintain mouse, rabbit, and pig tracheal explants. Notably, intact airway tissue can be cryoprese
