PURPOSE To isolate, culture, and characterize goblet cells from the conjunctiva of rats. METHODS Conjunctival tissue was surgically removed from Sprague-Dawley rats. Goblet cells were then isolated from the nictitating membrane and fornix using explant cultures. Cells derived from the explants were grown and propagated in RPMI medium supplemented with 10% fetal bovine serum. They were charact...

The understanding of adipose tissue development is crucial for the treatment of obesity-related diseases. Adipogenesis has been extensively investigated at the gene and protein levels in recent years. However, the alterations in protein glycosylation during this process remains unknown, particularly that of parthenogenetic embryonic stem cells (pESCs), a type of ESCs with low immunogenicity and...

AIM To develop specific fluorescent markers for melanoma tumor visualization, which would provide high selectivity and reversible binding pattern, by the use of carbohydrate-recognizing proteins, lectins, combined with the physical ability for imaging deep in the living tissues by utilizing red and near infrared fluorescent properties of specific rare-earth doped nanocrystals (NC). METHODS B1...

PURPOSE The intravitreal membrane (IVM) is a membranous structure between the primary and secondary vitreous bodies in developing mammalian eyes. In this study, for the first time the histogenesis of the IVM and the relationship between the hyaloid vasculature and the IVM was characterized in newborn mice. METHODS Eyes of mice less than 12 days old were fixed and embedded. From these, serial ...

The authors investigated the life cycle of Epstein-Barr virus (EBV) in keratinocytes of oral hairy leukoplakia by combining immunohistochemistry. DNA in situ hybridization, and lectin histochemistry with electron microscopy. Diffuse-staining components of the EBV early antigen complex (EA-D), EBV 150-kd capsid antigen (VCA), EBV membrane antigen (gp350/220), and double-stranded DNA were labeled...

Twenty lectins with different carbohydrate affinities, including five new lectins purified from fungi,were used for histochemical examination of carbohydrate determinants in rat ovaries and endometrium under experimental hyper- and hypothyroidism. In the ovaries of control rats, lectin binding was detected predominantly in the zona pellucida and corona radiata of growing follicles, luteocytes, ...

The main and accessory olfactory systems of certain mammals (e.g., rodents, ungulates, and carnivores) have been investigated using lectin histochemistry to probe for sugar residues that may reflect physiological aspects of signal transduction or development. Morphologically, the vomeronasal organs (VNOs) of strepsirrhine primates (lemurs and lorises) are typical of functional VNOs in other mam...

The effect of a practical plant protein-based diet containing vegetable oils (VO) as the major lipid source on the mucosal carbohydrate pattern of the intestine was studied in gilthead sea bream Sparus aurata challenged with the myxosporean parasite Enteromyxum leei. Fish fed for 9 mo either a fish oil (FO) diet or a blend of VO at 66% of replacement (66VO diet) were exposed to parasite-contami...

BACKGROUND Endometriosis is a common cause of infertility and pelvic pain. Lectin histochemistry has shown that glycan expression is a sensitive marker of differentiation in the normal endometrium. Endometrial biopsies were taken during the implantation window from women with subfertility and advanced (stage III and IV) endometriosis to evaluate specific glycans bound by lectins from Dolichos b...
