Contractility wins over the polarity pathway in a tug-of-war to position a cytokinesis-like actomyosin ring at the equator of notochord cells.

Novel insights into LIS1-dependent regulation of cell membrane contractility and cleavage axis specification identify a key molecular network regulating mitoses of neural progenitors and somatic cells during development.

Cannabinoids inhibit neuronal expansion and growth through the rapid contraction of actomyosin.

The Rho kinases ROCK1 and 2 act redundantly in regulating cell proliferation and their depletion causes cellular senescence.

Protein phosphatase 1 activity promotes cohesive collective cell migration by restricting actomyosin contractility to the periphery of the collective and maintaining proper cadherin–catenin complex protein levels at cell–cell junctions.

Deep penetration and transmission of mechanical force to regulate ER functions depends on not only the passive cytoskeletal support, but also the active actomyosin contractility, which is dispensable for mechanotransduction at the plasma membrane.

“Discontinuous” and “Continuous” migration modes are divergent mesenchymal migration strategies that arise spontaneously in parallel in an equilibrium modulated by cell-matrix attachment and actomyosin contractility.

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.
