oligodendrocyte

(ol?i-go-den'tro-sit) [? + ? + kytos, cell]
A glial cell found most commonly in axon tracts; it myelinates axons in the central nervous system just as Schwann cells myelinate axons in the peripheral nervous system. Oligodendrocytes are neuroectodermal cells that originate from different precursors in the neural tube than astrocytes; later, stem cells in the subependymal layer can continue to generate new oligodendrocytes. Mature oligodendrocytes wrap neighboring axons in myelin, and some oligodendrocytes can simultaneously wrap many axons. However, not all oligodendrocytes myelinate axons.
Synonym: oligodendroglia See: illustration

oligodendrocyte

A connective cell of the central nervous system (glial cell) that participates in the formation of the myelin sheaths of nerve cell axons.

Oligodendroglial cells are primary targets of the virus and exhibit nuclear enlargement with cytopathic effect, specifically a purple, ground-glass appearance (Figure 3, D).
(57) It is unclear, though, whether this histologic appearance is truly reflective of a derivation from oligodendroglial cells. Alternatively, these cells may be derived from more primitive tumor stem cells that can differentiate along a line of oligodendroglial differentiation.
