Stereological examination of placenta at 28 dpc. At 28 dpc, immunodetection of vimentin to label fetal capillaries was performed on labyrinthine area sections from the control group (a) and the exposed group (b). Black immunostaining represents fetal vessels (FV), blue cells are trophoblasts cells (T) and the white head arrows show circulating cells in maternal space (MS). Volume fraction of trophoblast (c), fetal capillaries (d) and maternal blood space (e) and surface density of fetal capillaries (f) were quantified. All data are expressed as median [Q1; Q3] (*p < 0.05, **p < 0.01, ***p < 0.001, compared with control group)
