Development of Oligodendroglia and Myelin
Myelin sheaths formed by oligodendrocytes (OLs) wrap around neuronal axons and allow for saltatory conduction of nerve impulses, significantly increasing the speed of electrical signal transmission. The development of oligodendrocyte lineage consists of several coordinated steps.Hao, Huang, Xiaofeng, Xu, Mengsheng, Qiu

Oligodendrocytes, the myelin forming cells of the central nervous system, were isolated from bovine white matter by trypsinization and sucrose gradient centrifugation, according to the method of Poduslo and Norton (l). The isolated cells were characterized biochemically by their composition and specific activity of several enzymes (2), and ...

Archives of Neurology & Psychiatry, 1929
The origin of the oligodendroglia is still a debated question. This cell, which Cajal called the "third element" of the brain, apparently has an origin different from that of the microglia. Del Rio Hortega is an advocate of the mesodermic origin of the microglia, although his view is not yet entirely accepted.

Vacuolation of oligodendroglia in neoplastic perifocal edema
Acta Neuropathologica, 1976Vacuolation of oligodendroglia, a new type of cytopathological change, has been described. The change is observed frequently at the perifocally edematous cerebral white matter adjacent to the metastatic lesions of carcinoma from the lung in all three cases examined. It is also present occasionally in association with astrocytoma.

Partial purification of a novel mitogen for oligodendroglia
Journal of Neuroscience Research, 1995AbstractA protein with a MWapp of 50–70 kDa isolated from the salt extract of crude membranes from neonatal rat brain increases the numbers of oligodendroglia in mixed glial cultures prepared from neonatal rat cerebral white matter. After partial purification by ion exchange and gel exclusion chromatography, and elution from an SDS‐polyacrylamide gel ...

Antibodies to Oligodendroglia in Patients with Multiple Sclerosis
New England Journal of Medicine, 1977We demonstrated antibodies to isolated oligodendrocytes and to oligodendroglia in brain sections by indirect immunofluorescence technic in serums of 19 of 21 patients with multiple sclerosis. We also found such antibodies in three of five patients with subacute sclerosing panencephalitis and one of four patients with acute disseminated ...

Expression of vimentin by cultured astroglia and oligodendroglia
Journal of Neuroscience Research, 1989AbstractThe objective of this study was to determine whether vimentin expression by process‐bearing astroglia and oligodendroglia cultured from neonatal rat cerebral cortex resembled that in brain where vimentin is common in immature astroglia and a few subpopulations of mature astroglia, but is absent in oligodendroglia.

Patterns of oligodendroglia pathology in multiple sclerosis
Brain, 1994Patterns of inflammation, demyelination and oligodendrocyte pathology were studied in acute multiple sclerosis and during early and late exacerbations of chronic multiple sclerosis. Cells within lesions were identified by immunocytochemistry with markers for T lymphocytes, macrophages, oligodendrocytes and astrocytes. In addition, in situ hybridization

In search of human oligodendroglia for myelin repair
Neuroscience Letters, 2009Cell therapy appears as an exciting strategy for myelin repair in pathologies where oligodendrocytes are deficient or impaired, such as leucodystrophies and multiple sclerosis. Many studies indicate that several types of rodent cells, including neural stem and progenitor cells, play a beneficial role after grafting and induce functional recovery in ...

In vivo staining of oligodendroglia in the rabbit retina
Glia, 1994AbstractWe have discovered that a strongly fluorescent dye, sulforhodamine 101, when injected intravitreally in vivo, very effectively stains a class of star‐shaped cells in the innermost layers of the rabbit retina. The cells were strictly confined to the region containing medullated fibers and emitted dichotomously branching processes that ended up ...
