NG2 Cells in White Matter But Not Gray Matter Proliferate in Response to PDGF

Abstract excerpt

Glial cells that express the NG2 proteoglycan and the α receptor for PDGF (NG2 cells, polydendrocytes) make up the fifth major cell population that serves as oligodendrocyte progenitor cells in the postnatal CNS. Although recent studies have suggested differences in their proliferation and oligodendrocyte differentiation in gray and white matter, the mechanism underlying the observed differences has been unclear....
