Pituicytes, which were specialized glocytes of the posterior pituitary, had five ultrastructural variants: major cells, dark cells, granular cells, ependymal cells, and oncocytic cells.
Consistent SVA IHC staining occurred at the transitional epithelium of the renal pelvis and the urinary bladder (Figure 1, panel D) of 4 piglets; within epithelial cells of the choroid plexus of the cerebrum (8 piglets) and the tongue (5 piglets); and at the ependymal cells of the choroid plexus, vascular endothelium, and the enterocytes of the villi of the small intestine (2 piglets) (Table 2, http://wwwnc.

Ependymomas arise from the ependymal cells lining the central canal of the spinal cord; four subtypes have been described: cellular, papillary, clear cell, and tanicytic.
They're lined with ependymal cells, a type of glial cell which --among other things--secretes, circulates, and absorbs cerebrospinal fluid.
The cerebral aqueduct, an anatomically restricted access of the ventricular system, is lined with ependymal cells expressing AQP4 and inflammatory sequelae of IgG binding to AQP4 and it is thought that this is the region where scarring, occlusion, stenosis, or reduced compliance of the aqueductal channel leading to obstruction occurs [19].
Other histologic findings can include ependymal cells, choroid plexus papillary projections, ganglion cells, oligodendrocytes, spongioblasts, and pigment epithelium.

Ependymal cells that line these ventricles have hair-like extensions that are thought to promote the normal flow of fluid.
