Effects of CeO2NPs exposure on early placental development. A HE staining of uterine tissue on GD10 observed under light microscope (Upper scale bar = 200 μm, lower scale bar = 50 µm). EPC: ectoplacental cone, Ch: chorionic ectoderm. B HE staining of placenta tissue on GD12. MD: maternal decidual, SP: spongiotrophoblast, Lab: labyrinth (Scale bar = 200 μm). C The area of ectoplacental cone and chorionic ectoderm on GD10. D The area of maternal decidua, spongiotrophoblast and labyrinth of placenta on GD12. *P < 0.05 vs. control. E MCT1 and MCT4 immunofluorescence staining of placenta on GD12 (Scale bar = 100 µm)
