Paternal MHC expression on mouse trophoblast affects uterine vascularization and fetal growth.
The mammalian fetus represents a semiallograft within the maternal uterus yet is not rejected. This situation is particularly pronounced in species with a hemochorial type of placentation, such as humans and rodents, where maternal tissues and blood are in direct contact with fetal trophoblast and thus potentially with paternal antigens. The main polymorphic antigens responsible for graft rejec...
متن کاملMHC-dependent inhibition of uterine NK cells impedes fetal growth and decidual vascular remodelling
NK cells express variable receptors that engage polymorphic MHC class I molecules and regulate their function. Maternal NK cells accumulate at the maternal-fetal interface and can interact with MHC class I molecules from both parents. The relative contribution of the two sets of parental MHC molecules to uterine NK cell function is unknown. Here we show that, in mice, maternal and not paternal ...

متن کاملEffect of Attachment Training on Paternal-fetal Attachment
Background & aim: Paternal-fetal attachment develops an emotional relationship between father and his infant which can affect their future interactions. Therefore, the present study aimed to determine the effect of attachment training on paternal-fetal attachment. Methods: This clinical trial was conducted in Karmandan and 22 Bahman health centers in Mashhad in 2015. The participants of the stu...
متن کاملSuppression of trophoblast uterine spiral artery remodeling by estrogen during baboon pregnancy: impact on uterine and fetal blood flow dynamics.
The present study was conducted to determine the impact of suppressing trophoblast remodeling of the uterine spiral arteries by prematurely elevating estrogen levels in the first trimester of baboon pregnancy on uterine and umbilical blood flow dynamics. Uteroplacental blood flow was assessed by Doppler ultrasonography after acute administration of saline (basal state) and serotonin on days 60,...
