[Immunohistochemical characteristics of human brain vascular plexuses].

The paper gives the data of studying the cells belonging to neuroblast progeny in embryonic origin. Differentiation in these cells was studied by immunohistochemical assay using a number of neuronal markers. Expression of S-100, NCAM, and neuron-specific enolase was revealed in the epithelial layer of vascular plexuses. No neural proteins (neuron-specific beta-3 tubulin, neuron-specific enolase, major myelin protein, neurofilaments, S-100, NCAM, synapsin I, and nerve growth factor receptors) were found in the stroma and the walls of the vascular plexuses in the lateral ventricles of the human brain. Nerve fibers were detected in the asinine choroid artery branches, by using neuron-specific beta-3 tubulin antibodies.
