A precise sequence of left-right asymmetries, combined with mechanical constraints, is sufficient to drive the looped morphogenesis of the embryonic heart tube, with potential impact for congenital heart defects.
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.
PTEN organizes multicellular architecture by non-catalytic scaffolding of spatially localized β-Arrestin1/ARHGAP21/Cdc42 protein complexes to control mitotic spindle orientation, multicellular configuration and lumen formation.
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.
Analysis of a double mutant in the Hippo pathway transcription factors Yap1 and Wwtr1 reveals novel roles for these factors in posterior body formation and epidermal morphogenesis in the vertebrate embryo.
Mechanical instabilities are shown to underlie the development of bacterial biofilm morphology, suggesting an ancient origin for mechano-morphogenesis, which is known to drive developmental processes in tissues in higher organisms.
