Ultrastructural Visualization of Concanavalin A Binding Receptor Sites in Neoplastic and Non-Neoplastic Transitional Cell Epithelium of the Human Urinary Bladder
Abstract:Concanavalin A binding receptor sites in non-neoplastic and neoplastic transitional cell epithelium from tumour-bearing human urinary bladders were mapped ultrastructurally following successive incubation of vibratome slices with concanavalin A, peroxidase and diaminobenzidine. In the normal epithelium the reaction product was found in the plasma membranes of the basal cells. Some areas of the endoplasmatic reticulum and the discoid vesicles were reacting in all cell layers. In the neoplastic epithelium, react… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
