About 4% of the cells in the adult rodent brain are PDGFRA+ NG2+ glia, derived from the oligodendrocyte lineage. Rivers and colleagues constructed a transgenic mouse to fate map the PDGFRA+ glia.

Stereotyped oligodendrocyte generation from divided NG2 cells. To determine the temporal dynamics of NG2 cell differentiation into oligodendrocytes after division in vivo, we first performed pulse ...
