    Tunable molecular tension sensors reveal extension-based control of vinculin loading

    Andrew S LaCroix et al.
    A quantitative understanding of molecular tension sensor function enables the production of unique sensors with desired mechanical properties as well as the ability to distinguish between protein force and protein deformation in mechanosensitive processes.

    Transient external force induces phenotypic reversion of malignant epithelial structures via nitric oxide signaling

    Benjamin L Ricca et al.
    In a 3D culture model of breast epithelium, application of a short-timescale compression to single malignant cells promotes the long-timescale development of polarized, growth-arrested structures.

    Mechanical force induces mitochondrial fission

    Sebastian Carsten Johannes Helle et al.
    Mechanically stimulating mitochondria causes them to divide via the recruitment of the mitochondrial fission machinery to the mechanically strained site, showing that intracellular organelles can be mechanoresponsive.

    Mechanical instability and interfacial energy drive biofilm morphogenesis

    Jing Yan et al.
    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.

    Myosin II isoforms play distinct roles in adherens junction biogenesis

    Mélina L Heuzé et al.
    Myosin isoforms exhibit different functions in the formation of adherens junctions and the transmission of mechanical forces.

    Spatial patterning of liver progenitor cell differentiation mediated by cellular contractility and Notch signaling

    Kerim B Kaylan et al.
    Mechanical stress plays a cooperative role with Notch in biliary differentiation of liver progenitors, supporting a model of liver development in which biomechanical cues are key inducers of cell fate.

    Non-canonical Wnt signaling regulates junctional mechanocoupling during angiogenic collective cell migration

    Joana R Carvalho et al.
    Analysis of axial polarity distributions shows that Wnt5a regulates collective cell migration in vivo by stabilizing vinculin at adherens junctions and fine-tuning mechanocoupling between neighbouring cells.

    Differentiation alters stem cell nuclear architecture, mechanics, and mechano-sensitivity

    Su-Jin Heo et al.
    Nuclear reorganization and stiffening accompanies mesenchymal stem cell differentiation, resulting in increased sensitivity to mechanical perturbation.

    Calcium-mediated actin reset (CaAR) mediates acute cell adaptations

    Pauline Wales et al.
    Calcium influx during acute cell stimulation triggers a global actin reset in mammalian cells, which is linked to plasma membrane repair and transcription and has implications for our understanding of cell migration, cancer, inflammation and cell stress response.
