Under Pressure

As cells migrate going about their business for the body's good (such as in wound healing) or detriment (as in cancer metastasis) they test and respond to their immediate surroundings. This study (cells navigating microfluidic chambers shown) finds that exposure to prolonged periods of elevated hydrostatic pressure dials down a cell's ability to sense and respond appropriately to their surroundings

Lead the Follower

Computer modelling collective cell migration – such as occurs in wound healing, embryo development and cancer invasion – reveals the contributions to the speed of migration made by characteristics of the cells of the leader and follower rows

Formin Shapes

The role of proteins called formins – key to the assembly of cells' inner scaffold or cytoskeleton – in the mechanics of migration of highly adherent cells is revealed by inactivating certain formins by CRISPR-Cas9 technology

Facilitating Migration

A protein called VAPA on the membrane of the endoplasmic reticulum – a cell's largest organelle, and where proteins are produced – is vital for cell movement (motility) as it mediates cytoskeleton activity and regulates adhesion to the substrate at a migrating cell's leading edge

Growing to Order

Cells organise as they migrate or as tissue grows in ways analogous to liquid crystals. This study provides greater understanding of cell organisation taking into account the influence of adhesion between the cells and with their substrate

Cell Block

Cells are often on the move, but how they navigate obstacles is a little mysterious. Here researchers create a sort of assault course for young pre-osteoblasts – cells destined to develop into bone. A microscope zooms down from above capturing the scene after eight days of challenging growth around a hemispherical bump (cells seem to prefer valleys to mountains). But these cells, highlighted in red with DNA in blue, are adapting. They align their stress fibres – stretchy bundles of actin used to change their shape and direction. Researchers believe cells align some of their stress fibres in the direction of movement while others brace across the cell to limit bending. Cells working together means the tissue can reach out between these obstacles, like climbers strung together navigating a mountain pass (although a million times smaller). Such insights may suggest ways to support migrating cells during development, or tissues remodelling after injury.
