The present study describes, for the first time, the glycosidic content of boar bulbourethral glands using lectin histochemistry. Fourteen horseradish peroxidase- or digoxigenin-labelled lectins with different carbohydrate specificities were used in samples obtained from 3 healthy Landrace boars. The results obtained indicate that endpiece and duct cells synthesize and secrete mainly O-glycopro...
A panel of five biotinylated lectins was applied to study the presence and distribution of membrane carbohydrate residues in the normal laryngeal epithelium and in laryngeal squamous cell carcinomas (SCCs) of 86 patients with the avidin-biotin peroxidase complex technique. The lectin-binding pattern of well-differentiated SCCs was comparable to that of the spinous cells of the normal laryngeal ...
This review was focused on the salivary gland oligosaccharide chains studied by lectin histochemistry combined with exoglycosidase digestion. Glycoconjugates play an important role in many biofunctions and, generally, salivary mucins, which consist of numerous oligosaccharide chains attached at closely spaced intervals to a peptide backbone, serve as lubricants and protective agents, but in man...
Background and purpose : Despite the impressive progress in diagnosis and treatment of breast cancer, due to late diagnosis and metastasis to lymph nodes, it is still the leading cause of mortality in women. New studies showed a few changes in cell surface glycoconjugate in a few organs in process of neoplasia. The aim of the present study was to recognize Gal/GalNac in cell surface glycocon...
Background and purpose: Sclera and choroid as external and middle tunic of the eye, originate from the mesenchyme surrounding the optic cup. Neural crest cells have major contribution in mesenchyme development. Main part of transmitter signals in eyes development are extracellular matrix components and cell surface glycoconjugates. The purpose of this study was to recognize extracellular m...
