Biology of Submucosal Gland Stem Cells in the Airway

Project Summary Airway submucosal glands (SMGs) are known to contain reserve stem cells for the surface airway epithelium (SAE). In mice, this niche serves only the trachea; however, in larger mammals such as humans, pigs and ferrets, SMGs are present throughout the intralobar cartilaginous airways and may serve the broader function of maintaining the proximal conducting airway epithelium in the setting of disease. During the previous six funding cycles, this grant has used mouse and ferret genetic models to address multiple aspects of airway SMG biology, SMG stem/progenitor cell biology, and cystic fibrosis (CF) lung pathogenesis. This proposal aims to identify the subpopulations of…
