    Detailed analysis of chick optic fissure closure reveals Netrin-1 as an essential mediator of epithelial fusion

    Holly Hardy, James GD Prendergast ... Joe Rainger
    Chick optic fissure closure is a powerful new model system for epithelial fusion and has revealed Netrin-1 as a conserved and essential mediator of tissue fusion in multiple contexts.

    Contrasting parental roles shape sex differences in poison frog space use but not navigational performance

    Andrius Pašukonis, Shirley Jennifer Serrano-Rojas ... Lauren A O'Connell
    Extensive field studies in poison frogs reveal that sex and species differences in parental behavior drive differences in space use patterns but not navigational performance and highlight the interplay between androgen levels and poison frog spatial behavior.

    Binding and sequestration of poison frog alkaloids by a plasma globulin

    Aurora Alvarez-Buylla, Marie-Therese Fischer ... Lauren A O'Connell
    Alkaloid-binding globulin (ABG) is a novel protein discovered in the plasma of poison frogs that transports many alkaloids, with structural homology to mammalian hormone carriers and amphibian biliverdin-binding serpin.

    Eye morphogenesis driven by epithelial flow into the optic cup facilitated by modulation of bone morphogenetic protein

    Stephan Heermann, Lucas Schütz ... Joachim Wittbrodt
    The lens-averted domains of the optic vesicle are reservoirs of neuroretinal cells that flow into the developing optic cup in a process that is critically influenced by BMP signaling.

    Maternally regulated gastrulation as a source of variation contributing to cavefish forebrain evolution

    Jorge Torres-Paz, Julien Leclercq, Sylvie Rétaux
    Phenotypic evolution can originate from variations in very precocious developmental events, starting even before fecundation, during the fabrication of the egg in the mother's gonad.

    OTX2 represses sister cell fate choices in the developing retina to promote photoreceptor specification

    Miruna Georgiana Ghinia Tegla, Diego F Buenaventura ... Mark M Emerson
    A retinal gene regulatory network prevents the formation of alternative cell fates from non-stochastic retinal progenitor cells.

    CHARGE syndrome modeling using patient-iPSCs reveals defective migration of neural crest cells harboring CHD7 mutations

    Hironobu Okuno, Francois Renault Mihara ... Hideyuki Okano
    Neural crest cells differentiated from patient-derived cells with mutations in the chromatin remodeler CHD7 show defective delamination, migration and motility in vitro, and defective migration in chick embryos.

    Primary cilia deficiency in neural crest cells models anterior segment dysgenesis in mouse

    Céline Portal, Panteleimos Rompolas ... Carlo Iomini
    Primary cilia of neural crest-derived cells mediate Indian hedgehog-induced signal transduction in the periocular mesenchyme and are required for normal anterior segment development.

    Regulation of retinal axon growth by secreted Vax1 homeodomain protein

    Namsuk Kim, Kwang Wook Min ... Jin Woo Kim
    Secreted Vax1 homeodomain protein supports the development of optic chiasm by directly acting at the retinal ganglion cell axon.
