Elucidating the roles of microRNA-103a-3p in trophoblast invasion and SOX4-mediated extravillous differentiation induced by activin A [PDF]

Cell Death and Disease
The dysregulation of growth factors is associated with defective trophoblast invasion, which leads to uteroplacental malperfusion due to the inadequate remodeling of spiral arteries.

HAND1 controls the lineage bifurcation of trophoblast and amnion from human pluripotent stem cells [PDF]

Cellular and Molecular Life Sciences
Trophoblast and amniotic lineages, representing key extra-embryonic tissues, can be differentiated from human pluripotent stem cells (hPSCs) under chemically defined conditions.

Isolation of First-Trimester and Full-term Human Placental Hofbauer Cells

Bio-Protocol, 2021
The placenta is the crucial organ that regulates the health of both mother and fetus during pregnancy. The human placenta is composed of villous tree-like structures that embed into the maternal decidua.

Primitive haematopoiesis in the human placenta gives rise to macrophages with epigenetically silenced HLA-DR

Nature Communications, 2023
The generation of primitive macrophages remains a poorly understood process in humans. Here, the authors identify placental erythro-myeloid progenitors that give rise to foetal macrophages in the early human placenta and demonstrate that epigenetic ...

Maternal and Fetal PI3K-p110α Deficiency Induces Sex-Specific Changes in Conceptus Growth and Placental Mitochondrial Bioenergetic Reserve in Mice

Veterinary Sciences, 2022
Fetal growth is reliant on placental formation and function, which, in turn, requires the energy produced by the mitochondria. Prior work has shown that both mother and fetus operate via the phosphoinositol 3-kinase (PI3K)-p110α signalling pathway to ...

Elevated homocysteine activates unfolded protein responses and causes aberrant trophoblast differentiation and mouse blastocyst development

Physiological Reports, 2022
Hyperhomocysteinemia may arise from folate/vitamin B12 deficiency, genetic polymorphisms, kidney disease, or hypothyroidism. It is associated with an increased risk of early pregnancy loss and placenta‐related complications of pregnancy, including pre ...

Placental secretome characterization identifies candidates for pregnancy complications

Communications Biology, 2021
Napso et al. identify proteins from mouse placental endocrine cells and create a comprehensive secretome map of the placenta. The authors compare this secretome map with human placental datasets from women with pregnancy complications and demonstrate the

RNA-Seq reveals changes in human placental metabolism, transport and endocrinology across the first–second trimester transition

Biology Open, 2021
The human placenta is exposed to major environmental changes towards the end of the first trimester associated with full onset of the maternal arterial placental circulation.

Maternal and Intrauterine Influences on Feto-Placental Growth Are Accompanied by Sexually Dimorphic Changes in Placental Mitochondrial Respiration, and Metabolic Signalling Pathways

Cells, 2023
Adverse maternal environments such as small size, malnutrition, and metabolic conditions are known to influence fetal growth outcomes. Similarly, fetal growth and metabolic alterations may alter the intrauterine environment and affect all fetuses in ...

Menstrual flow as a non-invasive source of endometrial organoids

Communications Biology, 2021
Tereza Cindrova-Davies et al. present a method for deriving endometrial organoids using menstrual flow collected from women. The approach shows promise as a personalised and non-invasive way to investigate gynaecological conditions such as endometriosis ...
