The vomeronasal organ (VNO) detects signaling molecules that often prompt innate behaviors, such as aggression and reproduction. Vomeronasal sensory neurons, classified into apical and basal lineages based on receptor expression, have a limited lifespan and are continuously replaced from a common stem cell niche. Using a combination of single-cell RNA sequencing data, immunofluorescence staining and lineage tracing, we identified CXCR4 expression in proliferative stem cells and the basal neuronal lineage. Mice with a conditional knockout of Cxcr4 showed an increased number of SOX2-positive proliferative stem cells and enhanced basal neuronal lineage maturation. In addition, computational gene perturbation analysis revealed 87 transcription factors that might contribute to neurogenesis, among which was SOX2. Conditional knockout of Cxcr4 did not only disturb neuronal maturation, but also affected non-neuronal cell types, resulting in a decrease of basal lamina lining quiescent stem cells and an increase in sustentacular support cells. Together, these findings enhance our understanding how a common pool of stem cells can give rise to different cell types of the VNO, highlighting the distinct role of CXCR4 in this process.
