Progenitor cell capacity of NeuroD1‐expressing globose basal cells in the mouse olfactory epithelium

The basic helix‐loop‐helix transcription factor NeuroD1 is expressed in embryonic and adult mouse olfactory epithelium (OE), as well as during epithelial regeneration, suggesting that it plays an important role in olfactory neurogenesis. We characterized NEUROD1‐expressing progenitors, determined their progeny in the adult OE, and identified a subtle phenotype in ΔNeuroD1 ‐knockout mice. All olfactory sensory neurons (OSNs) derive from a NeuroD1...
