neu·rog·li·a

(nū-rog'lē-ă), This word is grammatically singular. Avoid the mispronunciation neurogli'a.
Nonneuronal cellular elements of the central and peripheral nervous system; formerly believed to be merely supporting cells but now thought to have important metabolic functions, in that they are invariably interposed between neurons and the blood vessels supplying the nervous system. In central nervous tissue they include oligodendroglia cells, astrocytes, ependymal cells, and microglia cells. The satellite cells of ganglia and the neurolemmal or Schwann cells around peripheral nerve fibers can be interpreted as the oligodendroglia cells of the peripheral nervous system.

glia cells

[glī′ə, glē′ə]
Etymology: Gk, glia, glue; L, cella, storeroom
neural cells that have a connective-tissue-supporting function in the central nervous system. Examples include astrocytes and oligodendroglial cells of ectodermal origin and microglial cells of mesodermal origin.

Second, for the production of glia cells and neurons in the postnatal brain, Lgl1 function is only required in the individual stem cell which is just in the process of generating a neuron or glia cell.
In other words, you require the entire orchestra for a symphony (generate neurons in embryonic cortex) but only an individual soloist for a solo (produce neurons or glia cells in postnatal brain).
In this experiment, the DNA staining revealed that efavirenz administration affects the staining intensity of nuclei in the neurons and glia cells of the superior colliculus and lateral geniculate body in the treated adult Wistar rats.
The human glia cells essentially took over to the point where virtually all of the glial progenitor cells and a large proportion of the astrocytes in the mice were of human origin, and essentially developed and behaved as they would have in a person's brain," said Goldman.
According to the researchers, damage to retinal cells in both fish and birds prompts the specialized Muller glia cells to start dividing again, and to increase their options by becoming a more general type of cell called a progenitor cell.
The team points out that several research groups have tried to stimulate the Muller glia cells to grow in lab dishes and in lab animals by injecting cell growth factors or factors that re-activate certain genes that were silenced after embryonic development.
Observations made during such studies suggested that the Muller glia cells could be artificially stimulated to start dividing again, and to show light-detecting receptors.
However, all those studies had failed to detect any regenerated inner retina nerve cells, except when the Muller glia cells were genetically modified with genes that specifically promote the formation of amacrine cells, which act as intermediaries in transmitting nerve signals.
With a view to resolving the discrepancy between what was detected in chicks and not detected in rodents, the researchers carried out a systematic analysis of the response to injury in the mouse retina, and the effects of specific growth factor stimulation on the proliferation of Muller glia cells.
Goldman attempted to find the precise chemical signaling responsible for instructing neural stem cells when to create neurons and when to create glia cells.
