    Large, long range tensile forces drive convergence during Xenopus blastopore closure and body axis elongation

    David R Shook et al.
    Blastopore closure in Xenopus is driven by two morphogenic mechanisms that have strongly context dependent effects on tissue movement and that generate tensile force across tissues: convergent extension, as expected, and, unexpectedly, convergent thickening.

    Micropattern differentiation of mouse pluripotent stem cells recapitulates embryo regionalized cell fate patterning

    Sophie M Morgani et al.
    Micropatterned differentiation of mouse pluripotent stem cells gives rise to regionally distinct cell types arising in embryos at gastrulation.

    Gene-free methodology for cell fate dynamics during development

    Francis Corson, Eric D Siggia
    Mathematical methods based on geometry that directly embody the developmental concepts of competency, commitment, and determination provide succinct descriptions of morphogenesis and allow quantitative predictions from fits to sparse genetic data in Caenorhabditis elegans.

    Gdf3 is required for robust Nodal signaling during germ layer formation and left-right patterning

    Jose L Pelliccia et al.
    Genetic analyses demonstrate that Gdf3/Vg1 is a maternal effect gene required for robust Nodal signaling during different phases of embryogenesis including germ-layer formation, Kupffer's vesicle morphogenesis, and left-right patterning.

    Maternal Gdf3 is an obligatory cofactor in Nodal signaling for embryonic axis formation in zebrafish

    Brent W Bisgrove et al.
    Maternal Gdf3 and Nodal are interdependent obligatory cofactors in the fundamental patterning of the vertebrate embryonic axis of zebrafish.

    Vg1-Nodal heterodimers are the endogenous inducers of mesendoderm

    Tessa G Montague, Alexander F Schier
    Nodal is assumed to be the sole inducer of mesendoderm, but the related signal Vg1 is as essential as Nodal in this process.

    Nodal patterning without Lefty inhibitory feedback is functional but fragile

    Katherine W Rogers et al.
    Lefty-mediated feedback inhibition of Nodal signaling mitigates signaling perturbations, but is dispensable for development.

    Inhibition of DYRK1A disrupts neural lineage specificationin human pluripotent stem cells

    Stephanie F Bellmaine et al.
    Small molecule inhibition of stem cell differentiation in vitro provides novel insight into how DYRK1A loss disrupts human nervous system development.

    A novel role for Ets4 in axis specification and cell migration in the spider Parasteatoda tepidariorum

    Matthias Pechmann et al.
    In the spider Parasteatoda tepidariorum the transcription factor Ets4 is needed for cumulus integrity, dorsoventral patterning and for the activation of hunchback and twist expression.
