Several major vascular tissues, such as the aorta-gonad-mesonephros region (AGM), yolk sac, and fetal liver have been confirmed to possess hematopoietic function. Recently, the placenta has been demonstrated as another hematopoietic organ. However, it is not conclusive whether the placenta possesses hematopoietic ability. Therefore, we undertook a series of experiments to study the hematopoieti...

Uterine natural killer (uNK) cells, a specific type of (NK) are important cells at the foeto-maternal interface in humans as well mice. uNK part innate lymphoid group 1. Especially mouse, but also rat, many vivo studies have been performed to evaluate role placental development. These shown that not indispensable pregnancy, they play an optimal decidual angiogenesis early trophoblast invasion a...

Human papillomavirus (HPV) is an epitheliotropic virus typically infecting keratinocytes but also possibly epithelial trophoblastic placental cells. In the present study, we set out to investigate whether HPV can be recovered from transabdominally obtained placental cells to avoid any confounding contamination by HPV-infected cervical cells. Thirty-five placental samples from women undergoing t...

background: infection with parvovirus b19 may cause fetal losses including spontaneous abortion, intrauterine fetal death and non-immune hydropsfetalis. the aim of this study is to determine the frequency of parvovirus b19 in formalin fixed placental tissues in lost fetuses using real-time pcr method.   methods : in this cross-sectional study, 100 formalin fixed placental tissues with unknown c...

Plasmodium falciparum infection during pregnancy may cause placental malaria and subsequently low birth weight, primarily through the placental sequestration of infected red blood cells. Measuring the burden of malaria during pregnancy usually involves determining the prevalence of placental malaria infection through microscopic examination of placental blood films, a difficult and error-prone ...

Decidual NK (dNK) cells, a distinct type of NK cell, are thought to regulate uterine spiral artery remodeling, a process that allows for increased blood delivery to the fetal-placental unit. Impairment of uterine spiral artery remodeling is associated with decreased placental perfusion, increased uterine artery resistance, and obstetric complications such as preeclampsia and intrauterine growth...

Differentiation of trophoblast giant cells is an early event during the process of murine embryo implantation. However, differentiation of secondary trophoblast giant cells in the rodent is still only partially understood, probably because of the lack of suitable in vitro models and cell markers. In order to advance our understanding of trophoblast differentiation, suitable in vitro models and ...

Intrauterine growth restriction (IUGR) affects up to 10% of pregnancies in Western societies. IUGR is a strong predictor of reduced short-term neonatal survival and impairs long-term health in children. Placental insufficiency is often associated with IUGR; however, the molecular mechanisms involved in the pathogenesis of placental insufficiency and IUGR are largely unknown. Here, we developed ...
