A, Representative photomicrographs of Sox2+ NSCs and EdU+ proliferative cells in E19 dentate anlage. Blue DAPI stain denoted cell nuclei. IUGR offspring of both sexes showed decreased percentages of Sox2+ NSCs in the VZ and migratory stream (MS). p = 0.022, IUGR males compared with sex-matched sham controls; p = 0.005, IUGR females compared with sex-matched sham controls. By contrast, IUGR offspring of both sexes showed similar percentages of EdU+ proliferative cells in VZ and migratory stream. Dotted eclipses delineate the area of dentate anlage manually traced in ImageJ. B, Representative photomicrographs of Tbr2+ INPs in E19 dentate anlage. IUGR female offspring showed an increased percentage of Tbr2+ INPs in the MS and dentate anlage (p = 0.01, IUGR females compared with sham females). IUGR males had a percentage of Tbr2+ INPs similar to that of sham males. Two-way ANOVA with Tukey’s HSD post hoc test was used to examine the effects of treatment (sham or IUGR), sex, or both sex and treatment on the percentages of Sox2+, EdU+, or Tbr2+ cells.
