From: Sex differences in placental structure and gene expression in ICR mice during embryonic development
Sex difference in the placental size between female and male ICR mice during embryonic stages.A Representative image of placental regions for quantification. B-E Sex differences in the total area of the JZ and LAB (B), JZ (C), LAB (D), the ratio of the JZ area to the total JZ and LAB areas (E) of ICR mice at E12.5 to E18.5. Sex difference was observed in the JZ at E14.5 (E12.5: n = 6 placentas from 2 pregnant mice; sex ratios: female: male = 6:8 and 10:3; E14.5: n = 6–9 placentas from 2 pregnant mice; sex ratios: 7:5 and 8:7; E16.5: n = 3 placentas from 1 pregnant mouse; sex ratio: 8:4; E18.5: n = 3 placentas from 1 pregnant mouse; sex ratio: 7:5). Data are presented as means (± SEM), **P < 0.01, *P < 0.05, unpaired t-test between sex differences in same stages.
