Increased Angiogenesis and Lymphangiogenesis in the Placental Villi of Women with Chronic Venous Disease during Pregnancy. [PDF]
Int J Mol Sci, 2020 Pregnancy is a period in a woman’s life associated with an increased risk of developing lower extremity chronic venous disease (CVD). Pregnancy-associated CVD is associated with changes in placental villi.

Human type 2 17beta-hydroxysteroid dehydrogenase mRNA and protein distribution in placental villi at mid and term pregnancy [PDF]
Reproductive Biology and Endocrinology, 2007 Background During human pregnancy, the placental villi produces high amounts of estradiol. This steroid is secreted by the syncytium, which is directly in contact with maternal blood.

Convergently evolved placental villi show multiscale structural adaptations to differential placental invasiveness. [PDF]
Biol LettDespite having a single evolutionary origin and conserved function, the mammalian placenta exhibits radical structural diversity. The evolutionary drivers and functional consequences of placental structural diversity are poorly understood.

Immune Cells in the Placental Villi Contribute to Intra-amniotic Inflammation. [PDF]
Front Immunol, 2020 Intra-amniotic (IA) inflammation is associated with significant morbidities for both the mother and the fetus. Prior studies have illustrated many of the effects of IA inflammation on the uterine lining (decidua) and membranous layers of the placenta at ...

Renalase and its receptor, PMCA4b, are expressed in the placenta throughout the human gestation
Scientific Reports, 2022 Placental function requires organized growth, transmission of nutrients, and an anti-inflammatory milieu between the maternal and fetal interface, but placental factors important for its function remain unclear.

Placental Mesenchymal Dysplasia: A Confusing Entity and the Definitive Role of Histopathology [PDF]
Research in Oncology, 2022 Background: Placental mesenchymal dysplasia (PMD) is a rare placental disease of poorly understood etiology. It is characterized by aneurysmal dilatation of the chorionic blood vessels, mesenchymal proliferation, and myxomatous degeneration of the stem ...

Evidence for HPV DNA in the placenta of women who resorted to elective abortion
BMC Pregnancy and Childbirth, 2021 Background It is believed that HPV infection can result in the death of placental trophoblasts and cause miscarriages or preterm birth. In clinical cases of placental villi positive for HPV DNA reported by other authors, contamination is suspected in the
