Fig. 5.

Cell proliferation in the ipsilateral DG and cortex 35 days after TBI or sham. TBI significantly increased the number of BrdU-positive cells in the ipsilateral DG (c and d) and cortex (g and h). The cells with BrdU (brown stained) that clearly localize to the nucleus (hematoxylin stained) are counted as BrdU-positive cells (i, arrows). Scale bars: 50μm (a-h); 25μm (i). The number of BrdU-positive cells is shown in (j). Data represent mean with SD. N (mice/group) = 6 (Sham-Wild); 8 (TBI-Wild); 6 (Sham-Null); 10 (TBI-Null).
