Figure 2.

Labeling of striatal progenitors. (A) Lentiviral vector injections were surgically targeted at the wall of the lateral ventricle adjacent to the medial striatum (MSt). The area outlined is depicted in B. (B) Many cells in the ventricular zone (VZ) were infected, as shown by virally mediated GFP expression in a coronal section. The ventricle is on the left side of the image. (C–E) GFP+ neuron in the striatum recently divided and incorporated BrdU (arrows). Dashed lines (E) indicate the planes used to generate orthogonal views of the Z-stack (YZ, XZ). Scale bars: 25 μm (B), 10 μm (C–E).
