Uberon definition : The epithelial component of the choroid plexus. Consists of cuboidal epithelial cells
surrounding a core of capillaries and loose connective tissue.;
Uberon synonym : epithelial tissue of chorioid plexus of cerebral hemisphere; epithelium of choroid plexus; epithelial tissue of choroid plexus; choroid plexus epithelial tissue;
Uberon Structure note : The CP epithelial layer is continuous with the ependymal cell layer that lines the
ventricles, but unlike the ependyma, the epithelial layer has tight gap junctions
between the cells on the side facing the ventricle (apical surface). These gap junctions
prevent the majority of substances from crossing the cell layer into the CSF; thus
the CP acts as a blood-CSF barrier;
