Stimulation of hCG protein and mRNA in first trimester villous cytotrophoblast cells in vitro by glycodelin A [PDF]

open access: yes, 2005
Aim: Human chorionic gonadotropin (hCG) is produced by fetal trophoblast cells and secreted into maternal circulation mainly in the first trimester of pregnancy.

Hyperactivated Wnt-β-catenin signaling in the absence of sFRP1 and sFRP5 disrupts trophoblast differentiation through repression of Ascl2

open access: yesBMC Biology, 2020
Background Wnt signaling is a critical determinant for the maintenance and differentiation of stem/progenitor cells, including trophoblast stem cells during placental development.

BPDE induces human trophoblast cell ferroptosis by up-regulating iron metabolism and promoting GPX4 proteasomal degradation

open access: yesEcotoxicology and Environmental Safety, 2021
Human trophoblast cells play important role in embryo-fetal development. However, trophoblast cells are sensitive to environmental carcinogens. Recently, we have discovered that BPDE inhibits trophoblast cell migration, invasion and proliferation, and ...

Application of a JEG-3 organoid model to study HLA-G function in the trophoblast

open access: yesFrontiers in Immunology, 2023
The human placenta is a unique temporary organ with a mysterious immune tolerance. The formation of trophoblast organoids has advanced the study of placental development.

Fetal-derived trophoblast use the apoptotic cytokine tumor necrosis factor-alpha-related apoptosis-inducing ligand to induce smooth muscle cell death. [PDF]

open access: yes, 2007
Remodeling of the uterine spiral arteries during pregnancy transforms them from high to low resistance vessels that lack vasoconstrictive properties. This process is essential to meet the demand for increased blood flow imposed by the growing fetus. Loss

Human amniotic fluid glycoproteins expressing sialyl Lewis carbohydrate antigens stimulate progesterone production in human trophoblasts in vitro [PDF]

open access: yes, 2004
Background: Progesterone is thought to mediate immune modulator effects by regulating uterine responsiveness. The aim of the study was to clarify the effect of transferrin and glycodelin A (former name PP14) as sialyl Lewis X-expressing glycoproteins on ...

Adhesive and degradative properties of human placental cytotrophoblast cells in vitro. [PDF]

open access: yes, 1989
Human fetal development depends on the embryo rapidly gaining access to the maternal circulation. The trophoblast cells that form the fetal portion of the human placenta have solved this problem by transiently exhibiting certain tumor-like properties ...

Fetal and trophoblast PI3K p110α have distinct roles in regulating resource supply to the growing fetus in mice

open access: yeseLife, 2019
Studies suggest that placental nutrient supply adapts according to fetal demands. However, signaling events underlying placental adaptations remain unknown.

Extracellular Vesicles of Porphyromonas gingivalis Disrupt Trophoblast Cell Interaction with Vascular and Immune Cells in an In Vitro Model of Early Placentation

open access: yesLife, 2023
Extracellular vesicles released by the primary pathogen of periodontal disease Porphyromonas gingivalis (Pg), referred to as outer membrane vesicles (OMVs), have been associated with the pathogenesis of systemic diseases like cardiovascular disease ...

Brucella abortus Infection of Placental Trophoblasts Triggers Endoplasmic Reticulum Stress-Mediated Cell Death and Fetal Loss via Type IV Secretion System-Dependent Activation of CHOP. [PDF]

open access: yes, 2019
Subversion of endoplasmic reticulum (ER) function is a feature shared by multiple intracellular bacteria and viruses, and in many cases this disruption of cellular function activates pathways of the unfolded protein response (UPR).
