Immunohistochemical staining illustrating neurogenesis in control and ischemic rats. (A,B) Single-labeled BrdU+ cells are more numerous (arrows) within a DG in 2VO, ischemic animal at 10 days. (C,D) Double-labeled neuroblasts show BrdU+ (red) and DCX+ (green) neuroblasts at 10 days. (E,F) Double-labeled cells show BrdU+ (green) and CaBP+ (red) neurons at 35 days. Calibration bar = 40 microns in all cases.
