Rationale: We report a rare case of a pregnant woman with placental mesenchymal dysplasia (PMD) and intrauterine growth restriction (IUGR) with a genetically normal fetus.

Patient Concerns: A 42-year-old woman Gravida I, Para I with pre-existent uncontrolled hypertension and uterine polyfibromatosis present at 30 weeks of gestation for diminished fetal activity during the last 2 days.

Diagnosis: Placental mesenchymal dysplasia associated with intrauterine growth restriction, hypertension, and uterine polyfibromatosis.

Intervention: A live male infant was delivered by emergency caesarean section.

Outcomes: The infant, weighing 700 g, died 4 days after birth due to a massive intracerebral hemorrhage.

Lessons: A careful examination should be done at every ultrasound in case of a fetus with IUGR to exclude some rare cases of placental pathologies. PMD can be a rare cause of IUGR with a genetically normal fetus.

South American camelids inhabit high-altitude environments characterized by hypoxia, influencing embryonic, fetal, and placental development. This study examined the term placenta morphology of alpacas (, N = 12) and the immunoexpression of antioxidant selenoproteins (SP). We hypothesize that the placenta of alpacas, adapted to high altitudes, has characteristics with other species also adapted to altitude.

Polycystic ovary syndrome (PCOS) is a common cause of infertility in women, characterized by metabolic and hormonal irregularities. We investigated the effects of placenta-derived mesenchymal stem cells (PDMSCs) and platelet-rich plasma (PRP), as well as their combination on follicular development, hormonal profile, inflammatory parameters, and insulin resistance in a model of PCOS. In this study, 25 female Wistar rats were randomly allocated into five groups: Sham (given a dose of 1 mL of a 0.

Placental mesenchymal dysplasia (PMD) is a rare placental pathology that sonographically mimics gestational trophoblastic diseases. However, mesenchymal dysplasia can be distinguished from other conditions by the presence of villous edema and the absence of trophoblastic proliferation in the placental tissue. This pathology has been demonstrated to be associated with fetal growth restriction, Beckwith-Wiedemann syndrome, some chromosomal abnormalities and intrauterine fetal demise.

Somatic cell nuclear transfer (SCNT) has been successfully employed across various mammalian species, yet cloned animals consistently exhibit low pregnancy rates, primarily due to placental abnormalities such as hyperplasia and hypertrophy. This study investigated the involvement of the Hippo signaling pathway in aberrant placental development in SCNT-induced bovine pregnancies. SCNT-derived cattle exhibited placental hypertrophy, including enlarged abdominal circumference and altered placental cotyledon morphology.

Background/aims: Epithelial-to-mesenchymal transition (EMT) plays a crucial role in hepatic fibrogenesis and liver repair in chronic liver disease. Our research highlights the antifibrotic potential of placenta-derived mesenchymal stem cells (PD-MSCs) and the role of phosphatase of regenerating liver-1 (PRL-1) in promoting liver regeneration.

Methods: We evaluated the efficacy of PD-MSCs overexpressing PRL-1 (PD-MSCsPRL-1) in a bile duct ligation (BDL)-induced rat injury model, focusing on their ability to regulate EMT.
