    Morphogenetic forces planar polarize LGN/Pins in the embryonic head during Drosophila gastrulation

    Jaclyn Camuglia, Soline Chanet, Adam C Martin
    Morphogenetic forces from tissue invagination orient cell division through a previously undescribed mechanism of force-dependent LGN/Pins polarization.

    Transcriptomic profiling of tissue environments critical for post-embryonic patterning and morphogenesis of zebrafish skin

    Andrew J Aman, Lauren M Saunders ... David M Parichy
    Single-cell transcriptomics enables functional dissection of signaling interactions that drive morphogenesis of complex organ systems.

    Kinesin superfamily protein Kif26b links Wnt5a-Ror signaling to the control of cell and tissue behaviors in vertebrates

    Michael W Susman, Edith P Karuna ... Hsin-Yi Henry Ho
    Kif26b, a new component of the evolutionarily conserved Wnt5a-Ror signaling pathway, is controlled by regulated proteolysis and plays crucial roles in mediating vertebrate embryonic tissue morphogenesis.

    Crumbs is an essential regulator of cytoskeletal dynamics and cell-cell adhesion during dorsal closure in Drosophila

    David Flores-Benitez, Elisabeth Knust
    The evolutionarily conserved polarity protein Crumbs links the regulation of cytoskeleton dynamics and cell-cell adhesion with epithelial morphogenesis.

    Genetic requirement of dact1/2 to regulate noncanonical Wnt signaling and calpain 8 during embryonic convergent extension and craniofacial morphogenesis

    Shannon H Carroll, Sogand Schafer ... Eric C Liao
    During zebrafish embryogenesis, dact1 and dact2 are necessary for axis lengthening and craniofacial morphogenesis, and the protease capn8 is misexpressed in dact1/2 mutants.

    Fog signaling has diverse roles in epithelial morphogenesis in insects

    Matthew Alan Benton, Nadine Frey ... Siegfried Roth
    Fog signaling with a narrow morphogenetic role in Drosophila has a deeply conserved function in epithelial morphogenesis across insects.

    The embryonic role of juvenile hormone in the firebrat, Thermobia domestica, reveals its function before its involvement in metamorphosis

    James W Truman, Lynn M Riddiford ... Michelle Herko
    This sesquiterpene hormone likely acted as a morphogenesis-to-differentiation switch in archaic embryos before it evolved its postembryonic function as the status quo regulator of insect metamorphosis.

    Retinal stem cells modulate proliferative parameters to coordinate post-embryonic morphogenesis in the eye of fish

    Erika Tsingos, Burkhard Höckendorf ... Joachim Wittbrodt
    3D niche topology imposes a spatially biased random stem cell loss, which is differentially fine-tuned in neural retina and retinal pigmented epithelium to regulate growth, shape, and cellular topology.

    Pitx2c orchestrates embryonic axis extension via mesendodermal cell migration

    Michelle M Collins, Hans-Martin Maischein ... Didier YR Stainier
    Expression of Pitx2c at the onset of gastrulation drives convergence and extension movements in the zebrafish embryo by promoting downstream pathways affecting chemokine signaling, integrin-ECM interactions, and planar cell polarity components.

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

    David R Shook, Eric M Kasprowicz ... Raymond Keller
    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.
