From embryonic development, postnatal growth and adult homeostasis to reparative and
disease states, cells and tissues undergo constant changes in genome activity, cell fate …

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 …

The deformation and flow of disordered solids, such as metallic glasses and concentrated
emulsions, involves swift localized rearrangements of particles that induce a long-range …

Epithelial cell monolayers show remarkable displacement and velocity correlations over
distances of ten or more cell sizes that are reminiscent of supercooled liquids and active …

Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays
and cementitious pastes to emulsions and physical gels encountered in food or biomedical …

The origin of rigidity in disordered materials is an outstanding open problem in statistical
physics. Previously, a class of 2D cellular models has been shown to undergo a rigidity …

Epithelial tissues act as barriers and, therefore, must repair themselves, respond to
environmental changes and grow without compromising their integrity. Consequently, they …

Tissues transition between solid-like and fluid-like behavior, which has major implications
for morphogenesis and disease. These transitions can occur due to changes in the intrinsic …

Dynamics is central to living systems. Many experiments in the last two decades have
revealed glassy dynamics in diverse biological systems, showing a transition between a …

We investigate the effects of cell division and apoptosis on collective dynamics in two-
dimensional epithelial tissues. Our model includes three key ingredients observed across …
