The APJ receptor and its two endogenous ligands, apelin and elabela, exert key roles in fetoplacental development. In adult, this system is altered by obesity but no data are available during pregnancy. We measured apelin and elabela levels in maternal plasma and cord blood and quantified placental gene expression of apelin, elabela and APJ in obes...

The study was designed to assess the effects of hypertension (HT) susceptibility genes polymorphisms in the development of preeclampsia (PE) in Caucasians from Central Russia. PE patients (n = 452) and women control group (n = 498) were genotyped for 10 polymorphisms of HT/blood pressure (BP) susceptibility genes (according to the previously publis...

The pathological decrease of fetal growth during gestation can lead to subsequent poor health outcomes for the fetus. This process is commonly controlled by the placenta, the interface between mother and baby during gestation. Sex-specific gene expression has been implicated in placental function, therefore, there is a need to determine if it is im...

Syngnathids (seahorses, pipefishes and seadragons) are among the few vertebrates that display male pregnancy. During seahorse pregnancy, males incubate developing embryos embedded in a placenta within a fleshy brood pouch, before expelling fully developed neonates at parturition. The mechanisms underpinning seahorse parturition are poorly understoo...

In human pregnancy, maternal platelet counts decrease with each trimester, reaching a reduction by approximately ten percent at term in uncomplicated cases and recover to the levels of the non-pregnant state a few weeks postpartum. The time when maternal platelets start to occur in the early human placenta most likely coincides with the appearance ...

Studies have shown that the maternal nutrition during critical periods of development not only influences fetal growth but also plays a significant role in determining the risk of chronic disease in later life through developmental 'programming'. The placenta acts as a tool for 'programming' as it has the ability to adapt according to the maternal ...

Early placental development lays the foundation of a healthy pregnancy, and numerous tightly regulated processes must occur for the placenta to meet the increasing nutrient and oxygen exchange requirements of the growing fetus later in gestation. Inadequacies in early placental development can result in disorders such as fetal growth restriction th...

The human placenta is a highly specialized organ that is responsible for housing, protecting, and nourishing the fetus across gestation. The placenta is essential as it functions among other things as the liver, lungs, and gut while also playing key immunological and endocrine roles. The structure and transport capacity of this temporary organ must...

Prolonged pregnancy describes a pregnancy that progresses beyond 42 weeks' gestation (294 days). In humans, prolonged pregnancy is associated with increasing perinatal mortality, neonatal compromise and birth by Caesarean section. The underpinning reasons behind these increased risks are unknown; one potential explanation is reduced placental funct...

Human reproductive success relies on the intricate interplay between the developing embryo and the maternal endometrium. These highly-coordinated interactions facilitate implantation, setting in motion a series of developmental programs to establish a sustained fetal-maternal interface. Understanding endometrial function and the early human embryo-...
