Radial glial cells, or radial glial progenitor cells (RGPs), are bipolar-shaped progenitor cells that are responsible for producing all of the neurons in the cerebral cortex. RGPs also produce certain lineages of glia , including astrocytes and oligodendrocytes .
The ependyma is made up of ependymal cells called ependymocytes, a type of glial cell. These cells line the ventricles in the brain and the central canal of the spinal cord, which become filled with cerebrospinal fluid. These are nervous tissue cells with simple columnar shape, much like that of some mucosal epithelial cells. [2]
Oligodendrocytes are a type of glial cell, non-neuronal cells in the central nervous system.They arise during development from oligodendrocyte precursor cells (OPCs), [8] which can be identified by their expression of a number of antigens, including the ganglioside GD3, [9] [10] [11] the NG2 chondroitin sulfate proteoglycan, and the platelet-derived growth factor-alpha receptor subunit (PDGF ...
Many of the neuroepithelial cells also divide into radial glial cells, a similar, but more fate restricted cell. Being a more fate restricted cell the radial glial cell will either generate postmitotic neurons, intermediate progenitor cells, or astrocytes in gliogenesis. During neuroepithelial cell division, interkinetic nuclear migration ...
The subventricular zone (SVZ) is a region situated on the outside wall of each lateral ventricle of the vertebrate brain. [2] It is present in both the embryonic and adult brain. In embryonic life, the SVZ refers to a secondary proliferative zone containing neural progenitor cells, which divide to produce neurons in the process of neurogenesis. [3]
Olfactory ensheathing cells (OECs), also known as olfactory ensheathing glia or olfactory ensheathing glial cells, are a type of macroglia (radial glia) found in the nervous system. They are also known as olfactory Schwann cells , because they ensheath the non- myelinated axons of olfactory neurons in a similar way to which Schwann cells ...
Oligodendrocyte progenitor cells (OPCs), also known as oligodendrocyte precursor cells, NG2-glia, O2A cells, or polydendrocytes, are a subtype of glia in the central nervous system named for their essential role as precursors to oligodendrocytes and myelin. [1] They are typically identified in the human by co-expression of PDGFRA and CSPG4.
Radial glial cells, also called radial glial progenitor cells, divide asymmetrically to produce a neuroblast and another radial glial cell that will re-enter the cell cycle. [5] [3] This mitosis occurs in the germinal neuroepithelium (or germinal zone), when a radial glial cell divides to produce the neuroblast. The neuroblast detaches from the ...
