DCX and stroke disorder: We noted vigorous post-stroke neurogenesis as evidenced by an increased number (2.2-fold, p = 0.02) of DCX+ cells in the aged brains of animals treated with fluoxetine as compared to the modest expression in the brains of control animals (Figure 6A vs 6B) so that the number of DCX+ in treated animals was almost similar to the number of DCX+ found in the subventricular zone (SVZ) of young animals ipsilateral to stroke (Figure 6C, 6D).
