    Human embryo polarization requires PLC signaling to mediate trophectoderm specification

    Meng Zhu et al.
    Functional analyses of in vitro fertilized, preimplanation human embryos reveal that the first lineage segregation depends on cell polarization signaling that is regulated by Phospholipase C (PLC) activity.

    Untwisting the Caenorhabditis elegans embryo

    Ryan Patrick Christensen et al.
    Open-source software can untwist images of live Caenorhabditis elegans embryos, allowing epidermal and neuronal cell position and morphology to be examined in previously inaccessible developmental time periods.

    Dynamics of primitive streak regression controls the fate of neuromesodermal progenitors in the chicken embryo

    Charlene Guillot et al.
    Inverse gradients of cell ingression and division in the epiblast allow the bipotent progenitors in the anterior streak to become the main progenitors for posterior axis formation from the tail bud.

    Oviductal estrogen receptor α signaling prevents protease-mediated embryo death

    Wipawee Winuthayanon et al.
    Cyclic estrogen signaling in oviduct epithelial cells suppresses oviduct luminal protease activity to allow survival and development of preimplantation embryos

    Cellular resolution models for even skipped regulation in the entire Drosophila embryo

    Garth R Ilsley et al.
    A statistical model is able to predict patterns of gene expression output in Drosophila embryos using only the cellular concentrations of transcription factors as input.

    Modelling the impact of decidual senescence on embryo implantation in human endometrial assembloids

    Thomas M Rawlings et al.
    The study of embryo-endometrial interactions in assembloid co-cultures identifies novel mechanisms of reproductive failure.

    Characterization of the finch embryo supports evolutionary conservation of the naive stage of development in amniotes

    Siu-Shan Mak et al.
    Finch embryos are laid at an earlier stage than other avian embryos and contain cells with similar properties to pluripotent embryonic stem cells from mice.

    An integrative transcriptomic atlas of organogenesis in human embryos

    Dave T Gerrard et al.
    Integrating human embryonic transcriptomes from 15 sites during organogenesis identifies novel expression signatures linked to congenital disorders and a new programme of non-coding gene expression.

    Utility of polygenic embryo screening for disease depends on the selection strategy

    Todd Lencz et al.
    Preimplantation screening of embryos using polygenic risk scores may substantially reduce risk for a given complex disease, but this effect depends on several quantifiable factors and raises significant ethical issues.

    Maternally provided LSD1/KDM1A enables the maternal-to-zygotic transition and prevents defects that manifest postnatally

    Jadiel A Wasson et al.
    Epigenetic reprogramming by LSD1/KDM1A acts at fertilization in mice to enable embryogenesis and prevent behavioural abnormalities.
