(A) After 2 weeks of treatment with saline or levetiracetam (LEV; 75
mg/kg), 2-month-old NTG and APP mice (n = 9–11 mice per genotype and
treatment) were sacrificed, and the percentage of Ki67+ Nestin+ dividing NSCs
was quantified. Two-way ANOVA: genotype (p < 0.01), treatment (p <
0.05). Scale bar, 100 μm.
(B) The total number of Nestin+ NSCs in NTG and APP mice treated with
saline or LEV. Two-way ANOVA: genotype (p < 0.05), treatment and genotype
interaction (p < 0.05). Scale bar, 100 μm.
(C) DCX expression in NTG and APP mice treated with saline or LEV.
Two-way ANOVA: treatment (p < 0.0001), treatment and genotype interaction
(p < 0.05). Scale bar, 100 μm.
*p < 0.05; **p < 0.01; ***p <
0.001; Holm Sidak post hoc test. Values indicate mean ± SEM. See also
