Culture of cryopreserved first trimester placental tissues to study syncytial renewal
Scientific ReportsEx vivo studies with first trimester placental tissues are crucial for understanding human placental development, and culturing placental villi in floating conditions is vital to mimic the natural setting.

Vaccinations During Pregnancy Protect the Mother–Infant Dyad and Are Generally Safe
Acta Paediatrica, EarlyView.ABSTRACT Aim Vaccination in pregnancy has a critical impact on mothers, foetuses and infants. The aim of this paper was to summarise key points presented by experts attending the 12th Maria Delivoria‐Papadopoulos Perinatal Symposium in March 2025 and further expand and update them.

PFAS exposure during pregnancy: Implications for placental health and functioning
Environment InternationalBackground: Animal studies have linked prenatal poly- and perfluoroalkyl substances (PFAS) exposures with impaired placental structure and function. In humans, only few studies have investigated such associations.

Acta Paediatrica, EarlyView.ABSTRACT Aims and Methods Advances in neonatal care have extended borderline survival to 22–24 post‐conceptional weeks. Present review discusses approaches for prolonging short pregnancies and prevention of serious morbidities in extremely premature infants born before 28 weeks of pregnancy.

Quantitative proteomic (iTRAQ) analysis of 1st trimester maternal plasma samples in pregnancies at risk for preeclampsia [PDF]
, 2012 A current major obstacle is that no reliable screening markers exist to detect pregnancies at risk for preeclampsia. Quantitative proteomic analysis employing isobaric labelling (iTRAQ) has been suggested to be suitable for the detection of potential ...

Chorionic Villi with Placental Hypoplasia
Annals of CirculationThe structure and proliferation of endothelial and muscle cells of the chorionic veins of the underdeveloped placenta were studied. Histological, histochemical, and morphometric studies of the fetal membrane of the placenta of 36 placentas of 280-300 g at 39-40 weeks of pregnancy were carried out in comparison with 15 placentas of 450-500 g.

The FEBS Journal, EarlyView.Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.

Role of matrix metalloproteinases 2 and 9 in ex vivo Trypanosoma cruzi infection of human placental chorionic villi [PDF]
, 2012 Background: Chagas' disease is caused by the haemophlagelated protozoan Trypanosoma cruzi (T. cruzi). During congenital transmission the parasite breaks down the placental barrier.

The Journal of Physiology, EarlyView.Abstract figure legend We investigated how environmental hypoxia and genetic adaptation to high altitudes jointly impact the development of the placental exchange surface in ways that might protect fetal growth potential. We used wild‐derived, lab‐born North American deer mice (Peromyscus maniculatus) from low‐elevation and high‐elevation environments (
