A tanycyte is a specialized ependymal cell and glial cell of the hypothalamus. Its body can line the third ventricle, while a long process extends toward underlying tissue. In the median eminence, tanycytic endings surround neurosecretory terminals near blood vessels.[ref]
Vascular endothelial cells promote acute plasticity in ependymoglial cells of the neuroendocrine brain by Sandrine De Seranno and others. Introduction and Figure 1; ventricular cell bodies, long processes and vascular end-feet
In cultured rat tanycytes, signals from endothelial cells altered actin organization through nitric oxide.[ref]
