    Radially patterned cell behaviours during tube budding from an epithelium

    Yara E Sanchez-Corrales et al.
    Quantitative analysis in quasi-3D reveals apically driven cell behaviours that are closely coordinated across the tissue to allow ordered tube invagination through a focal point.

    Chiral cell sliding drives left-right asymmetric organ twisting

    Mikiko Inaki et al.
    Left-right asymmetric rotation of the Drosophila hindgut is driven by "cell sliding," a novel cellular behavior induced by chiral cell deformation, in which cells change their position relative to subjacent neighbors as sliding directionally.

    Unified quantitative characterization of epithelial tissue development

    Boris Guirao et al.
    A new approach measures the respective participations of elementary cell behaviors – such as cell division, intercalation, shape change and death – in the shaping of animal tissues.

    SOX2 regulates acinar cell development in the salivary gland

    Elaine Emmerson et al.
    Establishment of the acinar lineage in the salivary gland requires SOX2 and parasympathetic nerves.

    Two-step regulation of trachealess ensures tight coupling of cell fate with morphogenesis in the Drosophila trachea

    Takefumi Kondo, Shigeo Hayashi
    The Drosophila tracheal fate is stabilized by the combination of transcriptional programs to control tissue architecture and tissue-level input sensitive to tubular geometry, ensuring the robust mechanism of organ determination.

    Analysis of cellular behavior and cytoskeletal dynamics reveal a constriction mechanism driving optic cup morphogenesis

    María Nicolás-Pérez et al.
    High-resolution live imaging analysis shows a constriction mechanism that drives zebrafish optic cup morphogenesis and highlights the role of the extracellular matrix in transmitting tensions beyond the cellular level.

    Evolutionary expansion of apical extracellular matrix is required for the elongation of cells in a novel structure

    Sarah Jacquelyn Smith et al.
    A new morphological structure evolved through extreme changes in cell height requires novel connections to an extracellular matrix network, which predates the origin of structure.

    Two consecutive microtubule-based epithelial seaming events mediate dorsal closure in the scuttle fly Megaselia abdita

    Juan Jose Fraire-Zamora et al.
    Evolutionary reduction in tissue number involves the simplification of the seaming process but not signaling during epithelial fusion.

    Rho1 activation recapitulates early gastrulation events in the ventral, but not dorsal, epithelium of Drosophila embryos

    Ashley Rich et al.
    Spatially and temporally patterned activation of the small GTPase Rho1 indicates that ventral-specific factors contribute to cell- and tissue-level behaviors during ventral furrow formation, the first step in Drosophila gastrulation.
