    Inverted formin 2 regulates intracellular trafficking, placentation, and pregnancy outcome

    Katherine Young Bezold Lamm, Maddison L Johnson ... Louis J Muglia
    Loss of Inverted Formin-2 impairs intracellular trafficking and trophoblast invasion, resulting in maternal hypertension and intrauterine growth restriction, which represents a novel model of impaired placental invasion that encompasses critical aspects of the great obstetrical syndromes.

    Innate immune signaling in trophoblast and decidua organoids defines differential antiviral defenses at the maternal-fetal interface

    Liheng Yang, Eleanor C Semmes ... Carolyn B Coyne
    Organoids developed from matched human placental tissue define differences in antiviral signaling between cell types comprising the maternal-fetal interface.

    VE-cadherin enables trophoblast endovascular invasion and spiral artery remodeling during placental development

    Derek C Sung, Xiaowen Chen ... Mark L Kahn
    VE-cadherin is required for trophoblast invasion of the maternal decidua and spiral arteries.

    Fetal growth delay caused by loss of non-canonical imprinting is resolved late in pregnancy and culminates in offspring overgrowth

    Ruby Oberin, Sigrid Petautschnig ... Patrick S Western
    Growth-delayed offspring generated from eggs that lacked normal epigenetic programming exhibited a remarkable capacity to undergo late gestational fetal growth recovery, despite inefficient placental function.

    Single cell transcriptional signatures of the human placenta in term and preterm parturition

    Roger Pique-Regi, Roberto Romero ... Nardhy Gomez-Lopez
    Parturition gene regulation across multiple cell-types and placental compartments is deciphered at single cell resolution, highlighting the common role of the NFKB pathway in both term and preterm birth.

    Mammalian forelimb evolution is driven by uneven proximal-to-distal morphological diversity

    Priscila S Rothier, Anne-Claire Fabre ... Anthony Herrel
    The diversification of hand bones in mammals was much more dynamic than those of the proximal and intermediate forearm, involving higher morphological diversity, stronger integration, and greater evolutionary lability at distal structures.

    A molecular portrait of maternal sepsis from Byzantine Troy

    Alison M Devault, Tatum D Mortimer ... Caitlin S Pepperell
    Mineralized placental tissue from Late Byzantine Troy enables the detailed reconstruction of genomes of mixed bacterial species responsible for maternal sepsis in the ancient world.

    Placental Malaria: Tackling variants with antibodies

    Elizabeth H Aitken, Stephen J Rogerson
    Antibodies targeting the protein that causes placental malaria can recognise multiple variants of the protein, which may help guide the development of new vaccines to protect pregnant women from malaria.

    Reproduction: What is a placental mammal anyway?

    Patrick Abbot, John A Capra
    Many developmental functions in marsupials and eutherian mammals are accomplished by different tissues, but similar genes.

    PM2.5 leads to adverse pregnancy outcomes by inducing trophoblast oxidative stress and mitochondrial apoptosis via KLF9/CYP1A1 transcriptional axis

    Shuxian Li, Lingbing Li ... Xietong Wang
    Airborne PM2.5 exposure triggers oxidative stress and mitochondrial apoptosis in placental trophoblast cells via the KLF9/CYP1A1 transcriptional axis, ultimately leading to adverse pregnancy outcomes.
