To understand the cytochemical properties of epididymal epithelial cells, the characteristics of glycoconjugates in the mouse epididymis were examined using the technique of lectin histochemistry combined with immunohistochemistry. Characteristic staining patterns depending on the type of lectins were observed in the epididymal epithelium. Principal cells expressed N-acetyl-D-galactosamine (GalNAc), N-acetyl-D-glucosamine (GlcNAc), and Fucose in the proximal region of the epididymis and Mannose, Glucose, and Galactose in the distal region of the epididymis. Basal cells expressed Mannose, Glucose, Galactose, and GlcNAc in the proximal region and Galactose in the distal region. On the other hand, clear cells expressed various sugar residues and differences among regions were not observed. Interestingly, principal cells, clear cells, and basal cells specifically reacted with Ulex Europaeus-Agglutinin I (UEA-I lectin), Maackia Amurensis-Lectin I (MAL-I lectin), and Griffonia simplicifolia Lectin I-B4 (GS-I B lectin), respectively. These findings indicate that the selectivity in lectin reactivity for distinct cell types and segment-dependent staining in the epididymis may be related to cellular and regional differences in function. Furthermore, because some lectins stain particular cells or cellular compartments selectively, these lectins could be useful markers for histopathological evaluation of diseases or diagnosis of male infertility.
