    Selective activation of FZD7 promotes mesendodermal differentiation of human pluripotent stem cells

    Diana Gumber et al.
    Selective activation of FZD7 signaling with an engineered WNT mimetic promotes early developmental programs, including endodermal lineage specification, in human pluripotent stem cells.

    Optogenetic investigation of BMP target gene expression diversity

    Katherine W Rogers et al.
    Optogenetic manipulation of BMP signaling indicates that diversity in BMP-dependent gene expression is not well explained by differential responses to BMP, and combinatorial signaling is a major driver of diversity.

    High-resolution transcriptional and morphogenetic profiling of cells from micropatterned human ESC gastruloid cultures

    Kyaw Thu Minn et al.
    Micropatterned differentiation of human ESCs generates gastrulation cell types – germ layers, extraembryonic, and primordial germ cells with primate characteristics – that show conserved sorting behaviors when dissociated and reseeded as single-cell mixture.

    Beyond the RNA-dependent function of LncRNA genes

    Tamer Ali, Phillip Grote
    Recent examples demonstrate that already the transcriptional activity at lncRNA genes does have an important function on gene regulation, while the produced non-coding RNA might be dispensable.

    Cadherin preserves cohesion across involuting tissues during C. elegans neurulation

    Kristopher M Barnes et al.
    A coordinated tissue movement during C. elegans central nervous system internalization reveals a novel role for HMR-1/cadherin in maintaining cohesion, and extends the concept of neurulation beyond vertebrates.

    Hedgehog signaling is required for endomesodermal patterning and germ cell development in the sea anemone Nematostella vectensis

    Cheng-Yi Chen et al.
    The dependence of Nematostella germ cell specification on zygotic Hedgehog pathway activity supports the hypothesis that the eumetazoan common ancestor segregated its germline by inductive signals rather than maternal determinants.

    Sox17 and β-catenin co-occupy Wnt-responsive enhancers to govern the endoderm gene regulatory network

    Shreyasi Mukherjee et al.
    Genomic analysis of Xenopus gastrula reveal that the transcription factor Sox17 interacts with the Wnt signaling effector ß-catenin on enhancers to regulate the transcriptional program underlying endoderm germ layer formation.

    Nodal and planar cell polarity signaling cooperate to regulate zebrafish convergence and extension gastrulation movements

    Margot LK Williams, Lilianna Solnica-Krezel
    Nodal signaling regulates gastrulation cell behaviors largely in parallel with planar cell polarity signaling and is sufficient for ex vivo extension of embryonic explants.

    Zebrafish embryonic explants undergo genetically encoded self-assembly

    Alexandra Schauer et al.
    Blastoderm tissue organization and patterning in zebrafish explants is driven by a genetically encoded and controlled self-assembly mechanism, rather than a bonafide self-organization mechanism.

    Zygotic pioneer factor activity of Odd-paired/Zic is necessary for late function of the Drosophila segmentation network

    Isabella V Soluri et al.
    Mechanisms for shaping the chromatin accessibility landscape operate during development to regulate how embryonic patterning information is interpreted at the level of gene regulatory networks.
