Unbiased stereological counts of BrdU+ nuclei were expressed as a percentage of sham operated VTN+/+ mice. This showed that the MCAO-induced proliferation in the SVZ occurred both in females (A) and male (B), but that only female VTN−/− mice had an even greater response. BrdU+/DCX+ cell counts in the SVZ of females (C) and males (D) confirmed that this was also true for neurogenesis. N = 4, 7, 4 and 4 mice in females and N = 5, 3, 7 and 3 in males. * p<0.05, ** p<0.01, **** p<0.0001, Sham vs. MCAO, # p<0.05, VTN+/+ vs. VTN−/− in MCAO mice (Two-way ANOVA followed by post hoc Tukey multiple comparisons).
