Collective cell migration is a key driver of embryonic development, wound healing, and
some types of cancer invasion. Here, we provide a physical perspective of the mechanisms …

Self-propelled particles include both self-phoretic synthetic colloids and various
microorganisms. By continually consuming energy, they bypass the laws of equilibrium …

Cell motion inside dense tissues governs many biological processes, including embryonic
development and cancer metastasis, and recent experiments suggest that these tissues …

Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

From coffee beans flowing in a chute to cells remodelling in a living tissue, a wide variety of
close-packed collective systems—both inert and living—have the potential to jam. The …

Ranging from subcellular organelle biogenesis to embryo development, the formation of self-
organized structures is a hallmark of living systems. Whereas the emergence of ordered …

The mechanical behaviour of cells is largely controlled by a structure that is fundamentally
out of thermodynamic equilibrium: a network of crosslinked filaments subjected to the action …

Cell migration is important in many biological processes, including embryonic development,
cancer metastasis and wound healing. In these tissues, a cell's motion is often strongly …

This review summarizes theoretical progress in the field of active matter, placing it in the
context of recent experiments. This approach offers a unified framework for the mechanical …

The epithelial-to-mesenchymal transition (EMT) and the unjamming transition (UJT) each
comprises a gateway to cellular migration, plasticity and remodeling, but the extent to which …
