Choroid plexus and ependymal cells in CSF cytology
Clinical Neurology and Neurosurgery, 1986Choroid plexus and ependymal cells were only demonstrated in 10 of a series of 2620 CSF cytograms. Choroid plexus cells sometimes stained positive for acid phosphatase while in ependymal cells this enzyme activity was not observed. Choroid plexus and ependymal cells in CSF were found to be associated with various neurological disorders involving mainly

Spinous extensions on ciliary necklaces in ependymal cells
Cell and Tissue Research, 1981In ependymal cells of the mouse the neck region of all cilia examined by means of transmission electron microscopy exhibited rows of electron-dense spines. THese structures correspond to ciliary necklace reported from freeze-etch studies, a structure presumed to serve as an energy-regulating system in motile cilia.

Notch keeps ependymal cells in line
Nature Neuroscience, 2009The ependymal cells lining the lateral ventricles are not stem cells, but a study now shows that they can be activated to generate neuroblasts in a stroke model, and mature olfactory bulb neurons when Notch signaling is disrupted.

Viral Receptors on Isolated Murine and Human Ependymal Cells
Science, 1982Viruses that infect ependyma cause ependymitis in humans and hydrocephalus in experimental animals. We report that reovirus type 1 (which induces hydrocephalus in mice) binds to the surface of isolated human and murine ciliated ependymal cells. With the use of recombinant viral clones, the binding property was mapped to the type 1 viral hemagglutinin ...

Ultrastructural evidence that ependymal cells are infected in experimental scrapie
Acta Neuropathologica, 2008During the last stage of infection in the experimental scrapie-infected hamster model, light microscopy reveals typical immunostaining of PrPsc in the subependymal region and at the apical ependymal cell borders. Whereas the subependymal immuno-staining is known to originate from extracellular amyloid filaments and residual membranes of astrocytes as ...

Ultrastructure of ependymal cells in primary cultures of cerebral cortex
Journal of Neuroscience Research, 1987AbstractUltrastructural features of ependymal cells growing in primary cultures of dissociated cerebral cortical tissue were investigated using electron microscopy. The ependyma exhibited a specific orientation in tissue culture such that the cell surface corresponding to the apical surface in situ was directed toward the culture medium.

Ependymal and choroidal cells in culture: Characterization and functional differentiation
Microscopy Research and Technique, 1998During the past 10 years, our teams developed long-term primary cultures of ependymal cells derived from ventricular walls of telencephalon and hypothalamus or choroidal cells (modified ependymal cells) derived from plexuses dissected out of fetal or newborn mouse or rat brains.
