From: Nav1.7 is the predominant sodium channel in rodent olfactory sensory neurons
Na v 1.7 mRNA expression in olfactory epithelium using in situ hybridization. In situ hybridization signal is exhibited by olfactory sensory neurons (OSN) in the olfactory epithelium. Sustentacular cells (SC) do not express Nav1.7 mRNA signal above background levels. Inset: Increased magnification demonstrates Nav1.7 in situ hybridization signal in the peri-nuclear cytoplasm of OSN. The cell boundaries of two OSN that exhibit robust Nav1.7 signal are demarcated by dotted lines; the DAPI-labeled nuclei of these cells are indicated by arrows.
