part of part of tanycyte hypothalamus cell tanycyte of vascular organ of lamina terminalis 2025-06-04T10:27:59Z A specialized, non-ciliated ependymal glial cell located in the ventricular wall of the organum vasculosum of the lamina terminalis (OVLT) and characterized by elongated basal processes extending into the parenchyma to contact fenestrated capillaries. In mice, it is characterised by the expression of tight junction proteins (claudin 1, occludin, ZO-1) forming a continuous honeycomb junctional pattern. This cell contributes to a functional blood–cerebrospinal fluid (CSF) barrier at the ventricular interface of the OVLT. tanycyte-like ependymal cell of OVLT tanycyte-like cell of OVLT Tanycyte-like cells in CVOs supraoptic crest
