Immunohistochemistry of Snail and e-cadherin expression in normal definitive rat placenta. The photomicrographs show that Snail (stained red) is present in the nuclei of spongiotrophoblast cells of the junctional zone. E-cadherin (stained brown) is localized to the SynTB of the labyrinth (A). Snail positivity is also found in mononuclear sinusoidal TGC in some sinusoids positioned close to the junctional zone (arrow) (B)
