Fig. 4From: Maternal exposure to nano-titanium dioxide impedes fetal development via endothelial-to-mesenchymal transition in the placental labyrinth in miceTiO2 NPs exposure decreased vascular density in the placenta. a, b Laminin was used to label the placental blood vessels. The laminin staining areas and intensities decreased after TiO2 NP exposure. Data are presented as mean ± SEM. n = 3 placentas from 3 mice. **p < 0.01 as compared with the normal control (NC)Back to article page
