Astrocytes (green) in the context of neurons (red) in a mouse cortex cell culture 23-week-old fetal brain culture human astrocyte Astrocytes (red-yellow) among neurons (green) in the living cerebral cortex. Astrocytes are a sub-type of glial cells in the central nervous system. They are also known as astrocytic glial cells.
However, contrary to the prediction from optic nerve cultures, OPCs in white matter do not generate astrocytes. When the oligodendrocyte transcription factor Olig2 is deleted specifically in OPCs, there is a region- and age-dependent switch in the fate of OPCs from oligodendrocytes to astrocytes.

In 1988, about 18 acres (7.3 ha) of the Spanish Fort Site were listed on the National Register of Historic Places, due to the site's archaeological significance. Spanish Fort is one of five Sharkey County sites on the National Register, along with Leist A, the Rolling Fork Mounds, the Savory Site, and the Cary Site. The Little Spanish Fort is ...
Astrocytes participating in gliosis are referred to as reactive astrocytes. Gemistocytic astrocytes are assumed to be intensely active cells because the astrocytomas evolve into glioblastomas. Tritiated thymidine can be used to determine the rate of cell division and cellular origins of gemistocytic astrocytes, leading to the discovery of the ...
Reactive astrogliosis is a spectrum of changes in astrocytes that occur in response to all forms of CNS injury and disease. Changes due to reactive astrogliosis vary with the severity of the CNS insult along a graduated continuum of progressive alterations in molecular expression, progressive cellular hypertrophy, proliferation and scar formation.
