Figure 3. Irradiation reduced the number of hippocampal proliferating cells in both juvenile and adult brains.

Figure 3

Representative pictures showing cell proliferation (predominantly neural progenitor cells), as demonstrated by the numbers of Ki67-positive (red) cells, in the subgraular zone of the GCL in juvenile (A) and adult (B) hippocampi in sham (SH) controls and 24 h after IR. Ki67-positive cells decreased progressively after IR in both juvenile (C) and adult (D) brains. Scale bars, 50 μm. ***P < 0.001.
