OPCs in the ME of Naive Mice

(A) Scheme shows regions analyzed for BrdU⁺ cells.

(B) BrdU staining in the ME DG, SVZ, CC, Ctx, and St.

(C) Absence of neuronal progenitors (DCX) in the ME and CC compared with DG. Arrows indicate DCX⁺ BrdU⁺ cells.

(D) Images show OPCs (NG2) in the DG, CC, SVZ, and ME boxed in (A). Arrows indicate NG2⁺ BrdU⁺ cells.

(E) Images show NG2⁺ PDGFRa⁺ OPCs.

(F and G) Quantitative analysis of NG2⁺ BrdU⁺ cells in the DG, CC, SVZ, and ME as (F) mean number of NG2⁺ BrdU⁺ cells/mm². ^∗p = 0.013, ^∗∗p = 0.00079, and (G) as their mean percentage of BrdU⁺. ^∗p = 0.0007 (n = 4 for each group).
