• Horse olfactory epithelium consists of both OMP- and PGP 9.5-positive receptor cells, supporting cells including basal cells.
• Bowman’s gland acini contain PAS-positive neutral mucins and alcian blue pH 2.5-positive mucosubstances.
• Horse olfactory mucosa contains a variety of carbohydrate sugar residues with varying intensities.
The olfactory mucosae of the horse were examined by using histology and lectin histochemistry to characterize the carbohydrate sugar residues therein. Histological findings revealed that olfactory epithelium (OE) consisted of both olfactory marker protein (OMP)- and protein gene product (PGP) 9.5-positive receptor cells, supporting cells and basal cells with intervening secretory ducts from Bowman’s glands. Mucus histochemistry showed that Bowman’s gland acini contain periodic acid-Schiff (PAS) reagent-positive neutral mucins and alcian blue pH 2.5-positive mucosubstances. Lectin histochemistry revealed that a variety of carbohydrate sugar residues, including N-acetylglucosamine, mannose, galactose, N-acetylgalactosamine, fucose and complex type N-glycan groups, are present in the various cell types in the olfactory mucosa at varying levels. Collectively, this is the first descriptive study of horse olfactory mucosa to characterize carbohydrate sugar residues in the OE and Bowman’s glands.
