Summary: The conditioned media derived from human placenta-derived mesenchymal stromal cells (hPDMSCs) has shown pro-angiogenic and anti-inflammatory effects on a mouse model of preeclampsia, a severe pregnancy-related syndrome characterized by hypertension, proteinuria, inflammation, and fetal growth restriction. It was found that the hPDMSCs-derived conditioned media could reverse the preeclampsia-like features, including reducing maternal blood pressure, proteinuria, and levels of inflammatory markers.

Summary: Preeclampsia is a serious complication of pregnancy that can lead to maternal death and long-term complications. This study aimed to identify new compounds that can reduce sFlt-1 and inhibit HIF-1a, a prohypertensive factor. The natural compound luteolin showed the strongest inhibition of sFlt-1 release, with over 95% reduction compared to the control group. Luteolin also reduced HIF-1a expression through the Akt pathway. This makes luteolin a potential novel treatment for preeclampsia.

Summary: Preeclampsia is a dangerous complication of pregnancy that can lead to maternal death and long-term complications. This study aimed to find new compounds to reduce placental sFlt-1 and discovered that luteolin showed the most potent inhibition of sFlt-1 release, with over 95% reduction. Luteolin was found to reduce sFlt-1 through inhibition of HIF-1 alpha, possibly via the Akt pathway.

Summary: In patients with severe preeclampsia (sPE), the upregulation of soluble Axl (sAxl) in maternal plasma is positively correlated with elevated levels of sFlt-1 and negatively correlated with placental NO synthase (eNOS). Elevated sAxl levels suppress proliferation and tube formation of endothelial cells, and promote cytotoxicity. The study also demonstrates that sAxl plays a role in systemic vascular injury through the regulation of key molecules of angiogenesis, contributing to the development of sPE.

Summary: The interaction between trophoblasts, stroma cells, and immune cells at the maternal-fetal interface is crucial for successful pregnancy outcomes. However, efficient experimental models are lacking to investigate this complex interplay. To address this challenge, a reliable method for generating placenta villi organoids (PVOs) from different pregnancies is developed, enabling the analysis of cellular components and genetic alterations. PVOs derived from patients with preeclampsia exhibit specific pathological features. The development of PVOs can provide insights into placenta development and placenta-related diseases.

Summary: Placental extracellular vesicles (EVs) play a crucial role in feto-maternal communication and their uptake by recipient cells involves various mechanisms such as time, concentration, energy-dependence, as well as phagocytosis and endocytosis. The interaction between placental EVs and recipient cells is mediated by integrins.

Summary: D6 is a scavenger receptor expressed in the human placenta that prevents excessive leukocyte tissue infiltration by internalizing chemokines. In preeclampsia, the D6 receptor is overexpressed in trophoblast cells but functionally impaired due to cytoskeleton destructuring. Enoxaparin can enhance D6 expression and improve cytoskeletal organization in trophoblast cells from preeclampsia patients.

Summary: The study revealed that even a non-lethal concentration of GBS infection causes placental inflammation and oxidative stress, reduces trophoblast invasion of endothelial cells, and increases the production of key factors CXCL-8 and IL-6. Treatment with uvaol can prevent most of the changes induced by GBS, mitigating the harm to both the mother and the fetus.

Summary: Irisin is a newly discovered exercise-mediated polypeptide hormone. Studies have shown that Irisin protects against cell death by reducing pro-apoptotic signaling cascades, inducing DNA repair pathways, and inhibiting Caspase 3 activity. Additionally, Irisin acts through the Akt signaling pathway to prevent apoptosis, increase levels of anti-apoptotic BCL2, and reduce ROS levels. These findings provide new insights into the role of Irisin in promoting cell survival and preventing apoptosis in the human placenta under pathological conditions.

Summary: Studies in the gravid rat model have shown that relaxin, a corpus luteal hormone, plays a key role in the circulatory changes of early pregnancy, including systemic vasodilation and increased arterial compliance. This study investigates whether the corpus luteum has a similar role in human pregnancy, and suggests that the absence of a corpus luteum in artificial cycles for embryo transfers is associated with impaired cardiovascular changes observed during the first trimester. It also explores the potential role of corpus luteal factors in reducing the risk of developing preeclampsia.

Summary: Preeclampsia is associated with endothelial dysfunction and increased cardiovascular risk in offspring. Our study reveals that downregulation of miR-1270 contributes to impaired ECFC function and endothelial barrier permeability through ATM overexpression. These findings provide new insights into the understanding of ECFC impairment associated with cardiovascular risk in preeclamptic offspring.

Summary: The use of frozen-thawed embryo transfer (FET) treatment has increased significantly over the past decade. While the artificial cycle regimen provides convenience in aligning thawing and transferring embryos, recent data suggest that it may pose risks to maternal and fetal health. Therefore, the use of artificial cycle regimens in ovulatory women should be discouraged based on existing evidence.

Summary: This study is the first to demonstrate an impairment of endothelial progenitor cell function in offspring of kidney-transplanted mothers. The presence of post-transplant serum also negatively affects progenitor cell function in offspring from uncomplicated pregnancies. Clinical studies should focus on long-term monitoring of offspring's cardiovascular health.

Summary: This study investigates the acceptance, hesitance, and attitudes of infertile female patients toward the COVID-19 vaccination. The results of an anonymous survey show that 92.1% of the participants received at least one dose of the vaccine, while 7.9% remained unvaccinated. Factors such as employment, trust in vaccination, willingness for other vaccinations during fertility treatment, and risk factors for severe COVID-19 influence the decision to vaccinate.

Summary: This study isolated arterial feto-placental endothelial cells from control and preeclamptic placentas to investigate the potential protective effects of hydroxychloroquine (HCQ) in an in vitro model of endothelial activation. The results showed that HCQ did not adversely affect wound healing and endothelial barrier integrity, and it had a slight regulatory effect on IL-8 and VCAM-1 gene expression in the presence of inflammation. These findings support the safety of HCQ and highlight the need for clinical trials to evaluate its therapeutic effects in preeclampsia.
