Abstract
The present study localizes and characterizes complex glycoconjugates in the seminal vesicles of the Japanese Shiba goat, using several carbohydrate histochemical procedures, including lectin techniques at light and electron microscopic levels. Glandular epithelial cells and luminal secretions were shown to contain neutral and acidic glycoconjugates with various saccharide residues, such as alpha-D-Man, alpha-D-Glc, alpha-L-Fuc, beta-D-Gal, GalNAc, GlcNAc, and NeuAc (sialic acid). The terminal oligosaccharide chains of sialoglycoconjugates present in the seminal vesicles were NeuAc alpha 2-3Gal beta 1-3GalNAc and NeuAc alpha 2-3Gal beta 1-4GlcNAc. In addition, in lysosomes of the glandular epithelial cells alpha-D-Man, alpha-D-Glc, GlcNAc and NeuAc (sialic acid) residues could be detected, the secretory vesicles contained alpha-L-Fuc, and the endoplasmic reticulum exhibited alpha-D-Man and alpha-D-Glc residues. The complex glycoconjugates with various sugar residues found in the seminal vesicles of the goat may be involved in various fertilization-related events.
