The extravillous endovascular trophoblast forms a plug, which occludes the terminal portion of the uterine spiral arteries during the first trimester of pregnancy, restricting blood flow and, therefore, O2 to the intervillous space [16]. This low O2 tension in the intervillous space is essential...
This phenomenon results in a shift from low to a higher O2 tension in the intervillous space at the end of the first trimester [73], [74]. This increase in the O2 level promotes differentiation of the trophoblast as well as the maturation of the placenta to become an exchange organ [63...
