Cells measure a vast variety of signals, from their environment's stiffness to chemical
concentrations and gradients; physical principles strongly limit how accurately they can do …

Collective cell migration in response to a chemical cue occurs in many biological processes
such as morphogenesis and cancer metastasis. Clusters of migratory cells in these systems …

Many eukaryotic cells chemotax, sensing and following chemical gradients. However,
experiments have shown that even under conditions when single cells do not chemotax …

When a single cell senses a chemical gradient and chemotaxes, stochastic receptor–ligand
binding can be a fundamental limit to the cell's accuracy. For clusters of cells responding to …

Chemotactic cells of eukaryotic organisms are able to accurately sense shallow chemical
concentration gradients using cell-surface receptors. This sensing ability is remarkable as …

Multicellular chemotaxis can occur via individually chemotaxing cells that are mechanically
coupled. Alternatively, it can emerge collectively, from cells chemotaxing differently in a …

Many types of cells are able to accurately sense shallow gradients of chemicals across their
diameters, allowing the cells to move toward or away from chemical sources. This …

Many eukaryotic cells are able to detect chemical gradients by directly measuring spatial
concentration differences. The precision of such gradient sensing is limited by fluctuations in …

Chemotacting eukaryotic cells are able to detect very small chemical gradients (<?
format?>∼<? format?> 1%) for a large range of background concentrations. For these …

Chemotactic eukaryotic cells are able to detect chemoattractant gradients that are both
shallow and have a low background concentration. Under these conditions, the noise in the …
