Clinical neuropathology, 2003
Ependyma-lined cystic lesions of the subarachnoid space are uncommon. They form a histologically heterogeneous group and have been referred to as epithelial, ependymal, glioependymal and neuroepithelial cysts depending on their respective histological characteristics.

Anomalous Ependyma Inducing Split Cord and Meningomyelocele?
Journal of Child Neurology, 1999The case is that of a female fetus of 17 to 18 weeks' gestation with major defects of the central nervous system: (1) The thoracic vertebrae demonstrated rachischisis, with segmental diplomyelia; the duplicated cords were dissimilar in size and lay side by side within a single meningeal sheath lacking a dividing septum or spur. Cranially to the divided

The ventricular ependyma of mice infected with Trypanosoma brucei
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1986The fine structure of ependymal cells lining the cerebral ventricles of normal mice and of mice infected with Trypanosoma brucei was examined by transmission electron microscopy. Most of the ependymal cells had been stripped from the ventricular surface of the brain in infected animals but some of the remaining ependymal cells contained intracellular ...

Non‐Neoplastic Lesions of the Ependyma: A Neuropathological Overview
NeuropathologyABSTRACTNon‐neoplastic lesions of the ependyma have been neglected to date in comparison with neoplastic lesions derived from the ependyma, that is, ependymoma. The ependyma has a simple structure: mono‐layered cuboidal cells covering the surface of the cerebral ventricles and the central canal of the spinal cord.

After cytokeratins were first detected in human choroid plexus tumors (Coakham et al. 1985; Coffin et al. 1985) their localization in the nonmalignant counterparts was shown in several species by various authors (Schwechheimer et al. 1985; Kasper et al. 1986a,b, 1987a; Doglioni et al. 1987). These studies demonstrated the presence of cytokeratins 8 and

Effects of cytochalasin B on the ependyma.
Scanning electron microscopy, 1980In order to analyse whether or not surface morphology and intracellular skeleton are interdependent, Cytochalasin B (CB), an agent which interferes with microfilaments, was introduced ino the brain ventricular system of adult rats. Following intraventricular application of CB for different periods of time (up to 6h) the animals were sacrificed and the ...

Applying different stereological techniques, the total ependymal volume in the spinal cord of mice was estimated to be 83 x 10(6) microns cubed, the number of cells to be 163,000 and the mean ependymal cell volume to be 510 microns cubed. Compared to choroid plexus cells in the third ventricle, the ependymal cells in the spinal cord contained a smaller

The ependyma of the ventriculus mesencephali in the rat.
Acta morphologica Academiae Scientiarum Hungaricae, 1978The ventriculus mesencephali in the rat proceeds in the colliculi posterior region from the mesencephalic aqueduct in the dorsal direction. The ependymal lining is formed by flat, cuboid and cylindrical cells. The cylindrical cells, which occur in all parts of the ventriculus mesencephali, are the most numerous. The cuboid cells are localized mainly in
