Ependymal and neural stem cells are close relatives

Stem Cell Reports
Multiciliated ependymal and neural stem cells are key cell populations of the subventricular zone. Recent findings revealed that at least a subpopulation of radial glial cells during embryogenesis can be bipotent and produce both neural stem cells and ependymal cells.

Ependymoma with Intraorbital Extracerebral Recurrence: Case Report

Brazilian Neurosurgery, 2019
Ependymomas are rare neuroepithelial tumors that originate from a type of glial cell called ependymal cell. In general, they correspond to ∼ 1.2 to 7.8% of all intracranial neoplasms, and to ∼ 2 to 6% of all gliomas. Although it corresponds only to ∼2 to

Identification of a Neural Stem Cell in the Adult Mammalian Central Nervous System

, 1999
New neurons are continuously added in specific regions of the adult mammalian central nervous system. These neurons are derived from multipotent stem cells whose identity has been enigmatic.

Bi- and uniciliated ependymal cells define continuous floor-plate-derived tanycytic territories

Nature Communications, 2017
Ependymal cells lining the adult brain ventricles are comprised of multiciliated cells and a rare subpopulation with two cilia (E2 cells) whose origin and function remain unknown.

Reversal of Postnatal Brain Astrocytes and Ependymal Cells towards a Progenitor Phenotype in Culture

Cells
Astrocytes and ependymal cells have been reported to be able to switch from a mature cell identity towards that of a neural stem/progenitor cell. Astrocytes are widely scattered in the brain where they exert multiple functions and are routinely targeted ...

Intracerebroventricular antisense knockdown of Gα_i2 results in ciliary stasis and ventricular dilatation in the rat

BMC Neuroscience, 2007
Background In the CNS, the heterotrimeric G protein Gαi2 is a minor Gα subunit with restricted localization in the ventricular regions including the ependymal cilia.

Expression of innate immune complement regulators on brain epithelial cells during human bacterial meningitis

Journal of Neuroinflammation, 2006
Background In meningitis, the cerebrospinal fluid contains high levels of innate immune molecules (e.g. complement) which are essential to ward off the infectious challenge and to promote the infiltration of phagocytes (neutrophils, monocytes).

The Role of Atypical E2fs in the Maintenance and Development of the Ependymal Cell Barrier

, 2016
The discovery of neural stem cells within the adult CNS has indicated an enormous potential in facilitating neuronal regeneration after injury. Studies from our laboratory have suggested that manipulation of the Rb/E2f pathway can directly impact ...
