Figure 6: Chimeric mice stained for GFP (green) and Nestin (red). (a) GFP+ cells can be seen along the needle track and infiltrating in the sub-granular zone (SGZ) of the dentate gyrus (DG) and the CSF fluid space ventral to the hippocampus (scale μm). (b) GFP+ cells in the SGZ of the DG. (c) Nestin+ cells in SGZ of the DG. Most of the GFP+ cells are in the hilus (also known as CA4). (d) Merged image illustrating coexpression of GFP and nestin in two cells (asterisks) in the immediate SGZ (scale μm).
