Pituicytes, which were specialized glocytes of the posterior pituitary, had five ultrastructural variants: major cells, dark cells, granular cells, ependymal cells
, and oncocytic cells.[sup] Among the five ultrastructural variants, granular pituicytes were observed in neurohypophysis at a high incidence and had similar histological features to GCT.[sup] In addition, thyroid transcription factor-1 (TTF-1) expression in nontumorous pituicytes, pituicytoma, and GCT of neurohypophysis indicated a common pituicyte lineage.[sup] Therefore, GCT of neurohypophysis was identified to arise from granular pituicytes.
In premature babies, MBL could promote the contact guidance of neuronal migration, interneuronal recognition, formation of bridges between migrating neurons and radial astrocytes fibers, myelinization, and tightening of the ependymal cell
barrier, during the ontogenic development of the brain.
Vasospasm of choroidal artery probably originates HCP through stenosing the aqueduct and impairing ependymal cells
after SAH .
TrxmRNA has been localized also in epithelial cells of the choroid plexus and the ependymal cells
of the ventricle and the secreting cells of the choroid plexus [25, 28].
When neural stem cells are harvested for growth in culture, however, the ependymal cells
are not removed along with them, and this can be a problem.
The scientists found that neighbouring "epithelial-like" ependymal cells
- not stem cells themselves - maintain a special structure that keeps neural stem cells "neurogenic," able to make new neurons.
The roof plate of the diencephalon appeared thin, formed of a single layer of ependymal cells
covered by vascular mesenchyme.
of chordate larvae are stem-like cells that form the adult nervous system.
Enlargement of arachnoid cysts can be caused by fluid secretion from ependymal cells
, fluid ingress secondary to an osmotic gradient, trapping of fluid by a ball/valve mechanism, (3) and strenuous venous pulsation produced during Valsalva manoeuvres.
The histological exam of the surgical specimen documented neural tissue with ependymal cells
, macrophages, and cells of germ line without neoplastic elements.
Recently, MCT4 has been shown to localize to the membrane of glial cells in the cerebellum  and the paraventricular nucleus, specifically in astrocytes and ciliated ependymal cells
, playing a significant nonmetabolic role in the neuroprotective mechanism of ischemic preconditioning (IPC) in the gerbil with transient cerebral ischemia .
