A reconstituted system has been developed that self-organizes into dynamic actin cortices capable of spontaneous polarization, similar to the initial cortical polarization observed in cells during embryogenesis and development.
Electrical and biomechanical stimuli directly bias cortical signal transduction and cytoskeletal waves, and the direct bias induced by an electric field develops slowly compared to the rapid surface-receptor-mediated response to chemotactic gradients.

Planar cell polarity (PCP) components and myosin show a parallel temporal polarization in the Ciona notochord and the mutual interaction between these proteins is required for proper tissue-wide polarity.
An unprecedented large-scale screen in mice for morphogenetic regulators of tissue development provides major new insights into the roles of Rho GTPases in diverse array of skin developmental processes.
Macrophages use integrin-dependent 3D movement and cell protrusiveness, which control cell motility and space exploration as a prerequisite for optimal clearance of particles and dead cells by macrophage networks.

In vivo live imaging reveals the trafficking dynamics of three cellular organelles in neocortical axons with single vesicle resolution and demonstrates activity-dependent changes.
