    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.

    Gastrulation: May the force be with you

    Shinuo Weng, John B Wallingford
    Understanding the coordination of the forces generated in embryos by two processes, convergent extension and convergent thickening, is key to understanding how a hollow sphere of cells develops into an elongated embryo.

    The genome of the crustacean Parhyale hawaiensis, a model for animal development, regeneration, immunity and lignocellulose digestion

    Damian Kao et al.
    The first malacostracan genome sequence will establish the genetically tractable Parhyale hawaiensis as a model organism in this key animal group.

    Mitotic spindle scaling during Xenopus development by kif2a and importin α

    Jeremy D Wilbur, Rebecca Heald
    An interaction between two proteins enables the spindle—the structure that segregates chromosome pairs during mitosis—to change size as cells divide.

    The Caenorhabditis elegans protein SAS-5 forms large oligomeric assemblies critical for centriole formation

    Kacper B Rogala et al.
    SAS-5 forms oligomers, through a trimeric coiled coil and novel dimeric domain, that are necessary for centriolar localisation of SAS-5 and for centriole duplication.

    ErbB expressing Schwann cells control lateral line progenitor cells via non-cell-autonomous regulation of Wnt/β-catenin

    Mark E Lush, Tatjana Piotrowski
    Schwann cell induced quiescence of mechanosensory progenitor cells is mediated by inhibition of Wnt/β-catenin signaling.

    A SLC4 family bicarbonate transporter is critical for intracellular pH regulation and biomineralization in sea urchin embryos

    Marian Y Hu et al.
    Cellular carbon accumulation systems are a fundamental prerequisite for biomineralization to stabilize pH and to supply inorganic carbon for CaCO3 precipitation under changing environmental conditions.

    Dkk2 promotes neural crest specification by activating Wnt/β-catenin signaling in a GSK3β independent manner

    Arun Devotta et al.
    Dkk2, a member of the Dikkopf family of Wnt antagonists, acts as a positive regulator of Wnt signaling during neural crest formation.

    Position- and Hippo signaling-dependent plasticity during lineage segregation in the early mouse embryo

    Eszter Posfai et al.
    Lineage specification and commitment are synchronized in the developing trophectoderm lineage of the mouse embryo, but are asynchronous events in the maturing inner cell mass, revealing a window of plasticity in this lineage.

    Lineage commitment of embryonic cells involves MEK1-dependent clearance of pluripotency regulator Ventx2

    Pierluigi Scerbo et al.
    Degradation and asymmetric inheritance during cell division of a core pluripotency regulator contributes to lineage commitment in the early Xenopus embryo.
