The vomeronasal organ (VNO) is critical for reproduction and social behavior in ruminants, including cattle. The present study examined the structure of the VNO and its epithelial cells in neonatal and adult Korean native cattle (Hanwoo), Bos taurus coreanae , using immunohistochemistry and lectin histochemistry. Histologically, the VNO comprised two types of epithelia: medial vomeronasal sensory (VSE) and lateral vomeronasal non-sensory epithelia (VNSE). Numerous blood vessels and nerve bundles were observed within the vomeronasal cartilage encased lamina propria. Immunohistochemistry revealed high expression level of protein gene product9.5 and moderate expression level of olfactory marker protein in the neuroreceptor cells of the VSE and occasionally in some ciliated cells of the VNSE in both neonates and adults. The properties of the glycoconjugates in the VNO were investigated using 21 lectins, most of which were expressed at varied intensities in the VSE and VNSE, as well as in the lamina propria. Several lectins exhibited variations in their intensities and localization between neonatal and adult VNOs. This study is the first descriptive lectin histochemical examination of the VNO of Korean native cattle with a focus on lectin histochemistry, confirming that the VNO of Korean native cattle is differentiated during postnatal development.
