NG2 glia
 | This article provides insufficient context for those unfamiliar with the subject. (December 2012) |
NG2 glia is a type of macroglia found in the central nervous system, which is distinct from astrocytes and oligodendrocytes.[1] They get their name from the expression of NG2 proteoglycan on their surface. Although their exact function is unknown, they are found engulfing nodes of Ranvier.[2] NG2 glia were believed to be the precursors of oligodendrocytes, but recent evidence suggests that they have distinct functions and divide very slowly.[3] From an evolutionary point of view, the NG2 glia attained more complexity in the mammals and primates.
