Immunohistochemical analysis of chemokine receptor expression in the mouse olfactory neuroepithelium. CXCR4 (green) was mainly located in neuronal stem cells and immediate neuronal progenitor cells (green); GAP43–labeled immature neurons (red) and OMP–labeled mature olfactory neurons (white). Neurogenesis in the olfactory epithelium was shown to depend on CXCR4 expression.
