Representative data showing doublecortin-immunoreactive (DCX+) cells in the subventricular zone (SVZ) (A-F) and subgranular zone (SGZ) (G-L) in age-matched control (A-C; G-I) compared to Pb-treated (D-F; J-L) animals surviving 4 months. Framed areas in left panel images are sequentially enlarged as middle and right panel images. Scale bar in (A) = 200 μm applying to left panels; equal to 200 μm for middle panels and 50 μm for right panels.
