Objectives: Four isoforms originating from alternative splicing of PGF gene have been reported for placental growth factor (PlGF). Main PlGF isoforms 1 and 2 have been associated with screening and diagnosis of pre-eclampsia (PE). Despite of the vast amount of research around PlGF in PE, protein levels of isoforms PlGF-3 and -4 have not been reported in human serum samples.
Study Design: In this study a PlGF-3 specific DELFIA research immunoassay based on a custom recombinant Fab binder was developed and characterized. Serum levels of a third PlGF isoform during pregnancy were determined and screening performance of PlGF-3 for PE and small for gestational age (SGA) was investigated.
Main Outcome Measures: Levels of serum and placental tissue PlGF 3 and predictive power of PlGF-3 for Pre-eclampsia and SGA.
Results: PlGF-3 was below the detection limit of 1.6 pg/mL in most of the serum samples collected during pregnancy. Detected protein levels of PlGF-3 were not associated to be predictive for PE or SGA. However, measurable, and relatively higher amounts of PlGF-3 was extracted from placental tissue samples.
Conclusion: Data obtained indicates that very low amounts of PlGF-3 is present in blood but significantly higher amounts of protein is present in placental tissue where it is prominently associated with cellular membranes.

Dermatologists have been interested in recent advancements in regenerative therapy. Current research is actively investigating the possibility of placental tissue derivatives to decelerate the skin aging process, enhance skin regeneration, reduce scarring, and prevent hair loss. Amniotic membranes (AM) play a crucial role in regenerative medicine as they serve as a suitable means of transporting stem cells, growth hormones, cytokines, and other essential compounds.

In this study, urea was used to decellularize and solubilize human placenta tissue. Then, different concentrations of ECM were composited with 8% alginate (Alg) and 12% silk fibroin (SF) for printing in order to produce a natural 3D construct that resembled bone tissue.

Background: Preeclampsia is a major challenge for obstetricians due to its severe impacts on maternal and fetal health. Lysine lactylation (Kla) derived from lactate is a novel type of post-translational modification which has been confirmed to affect the malignant progression of diseases as an epigenetic modifier. However, the systemic lactylome profiling of preeclampsia is still unclear.

This study investigated the consequences of perinatal exposure to Aroclor 1221 (A1221), a weakly estrogenic polychlorinated biphenyl (PCB) mixture and known endocrine-disrupting chemical (EDC), in female rats. Previous work has shown behavioral and physiological effects of A1221, and the current study extended this work to comprehensive transcriptomic profiling of two hypothalamic regions involved in the control of reproduction: the arcuate nucleus (ARC) and anteroventral periventricular nucleus (AVPV). Female Sprague-Dawley rats were fed a cookie treated with a small volume of A1221 (1 mg/kg) or vehicle (3% DMSO in sesame oil) during pregnancy from gestational days 8-18 and after birth from postnatal (P) days 1-21, exposing the offspring via placental and lactational transfer.

From fertilisation to delivery, calcium must be transported into and within the foetoplacental unit for intracellular signalling. This requires very rapid, precisely located Ca transfers. In addition, from around the eighth week of gestation, increasing amounts of calcium must be routed directly from maternal blood to the foetus for bone mineralisation through a flow-through system, which does not impact the intracellular Ca concentration.
