Figure 4: Increased neuroblasts in the hippocampal dentate gyrus of MECP2 transgenic mice.

(a) Experimental scheme for assessing new neuroblasts in the adult hippocampus. (b–e) Sample confocal images of immunostaining of DAPI, MCM2 and DCX. Arrows indicate BrdU+/DCX+ neuroblasts. Scale bar: (b–e), 20 μm. (f) The dentate gyrus of MECP2 TG mice exhibited increased BrdU+/DCX+ neuroblasts analyzed at 7 days after 4 doses of BrdU injections. (g) MECP2 TG mice had similar DG volume with WT mice. Values are Mean ± S.E.M (n = 4 animals for each genotype; **P < 0.01, ns: non-significant, student’s t-test).
