| Open AccessCell clusters softening triggers collective cell migration in vivo
Collective cell migration in embryonic tissues is triggered by cell softening due to a microtubule deacetylation pathway involving the mechanosensitive ion channel Piezo1.

Directed cell migration towards softer environments
Directed cell movement known as durotaxis, typically associated with cellular migration in response to a substrate gradient of increasing stiffness, is now shown to also occur in the opposite direction, following a gradient of decreasing stiffness.

Self-generated gradients steer collective migration on viscoelastic collagen networks
Cell clusters mechanically reorganize viscoelastic collagen networks, resulting in transient gradients in collagen density, alignment and stiffness that promote spontaneous persistent migration.

Microtubules tune mechanosensitive cell responses
Substrate-rigidity-dependent microtubule acetylation is now shown to be triggered by mechanosensing at focal adhesions, and in turn controls the mechanosensitivity of Yes-associated protein (YAP) translocation, focal adhesion distribution, actomyosin contractility and cell migration.

Enhanced substrate stress relaxation promotes filopodia-mediated cell migration
It is now shown that cells migrate robustly on soft, viscoelastic substrates with fast stress relaxation using a migration mode marked by a rounded cell morphology and filopodia protrusions extending at the leading edge.

Investigating the nature of active forces in tissues reveals how contractile cells can form extensile monolayers
It is now revealed, using cell cultures and in silico models, that weakening intercellular contacts is a fundamental process essential for switching from extensile to contractile tissue behaviour.

Extracellular matrix anisotropy is determined by TFAP2C-dependent regulation of cell collisions
The generation of aligned extracellular matrices by fibroblasts is shown to depend on cell reorientation following collision, leading to closer alignment of the cells’ long axes. This cell collision guidance depends on the transcription factor TFAP2C and localized regulation of actomyosin contractility.

Molecular basis for fluidization of cancer cells
A molecular pathway has been identified in the regulation of unjamming to overcome cancer cell migration and proliferation arrest leading to collective cell invasion.

Unjamming overcomes kinetic and proliferation arrest in terminally differentiated cells and promotes collective motility of carcinoma
A RAB5A-mediated, epidermal growth factor-dependent activation of endosomal ERK1/2 is identified as a key molecular route for a solid-to-liquid-like phase transition, sufficient to overcome kinetic and proliferation arrest in normal mammary epithelial assemblies and to promote collective invasion in breast carcinoma.

Endocytic reawakening of motility in jammed epithelia
Increased cellular expression of RAB5A, an important regulator of endocytic processes, brings epithelial cells from a jammed state to coordinated motion, and can facilitate wound closure, gastrulation and migration in constrained environments.

Conscripted by collagen
In atherosclerotic plaques, patterns of calcification — which have profound implications for plaque stability and vulnerability to rupture — are determined by the collagen's content and patterning throughout the plaque.

Lighting the way
Advances in photochemistry have profoundly impacted the way in which biology is studied. Now, a photoactivated enzymatic patterning method that offers spatiotemporal control over the presentation of bioactive proteins to direct cells in three-dimensional culture significantly expands the available chemical toolbox.

Collective cell guidance by cooperative intercellular forces
The mechanical stresses within and between cells inside an advancing cellular monolayer are mapped experimentally. Cellular migration is found to be oriented in the direction of maximum principal stress indicating that cells collectively migrate to maintain minimal local intercellular shear stress.
