Ncf1/Igfbp2 Signaling Regulates Airway Submucosal Gland Progenitor Fitness and Ionocyte Specification
Background Airway submucosal gland progenitors (SMGPs) serve as reserve stem cells for epithelial regeneration, yet mechanisms governing their long-term maintenance remain poorly understood. Here, we identify Ncf1/Igfbp2 signaling as a regulator of mouse SMGP fitness and epithelial lineage specification. Methods Mouse...
