Accumulation of mucus in airways of TMEM16A−/− mice. Mucus staining (PAS) in bronchi of wild type littermates (TMEM16Aflox/flox; TMEM16A+/+) and mice with an airway epithelial-specific knockout of TMEM16A (FOXJ1-Cre-TMEM16Aflox/flox; TMEM16A−/−). Strong accumulation of mucus in airway epithelial cells is observed in TMEM16A−/− mice. Bars indicate 20 μm (Benedetto et al., 2019).
