Automated single-cell motility analysis on a chip using lensfree microscopy. [PDF]
, 2014 Quantitative cell motility studies are necessary for understanding biophysical processes, developing models for cell locomotion and for drug discovery.

Dense active matter model of motion patterns in confluent cell monolayers [PDF]
, 2020 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 nematics.

A self-driven phase transition drives Myxococcus xanthus fruiting body formation [PDF]
, 2019 Combining high-resolution single cell tracking experiments with numerical simulations, we show that starvation-induced fruiting body (FB) formation in Myxococcus xanthus is a phase separation driven by cells that tune their motility over time.

Bacterial Motility in Biofilm Under Shear Flow
Chemical Engineering Transactions, 2022 A key role in bacteria surfaces contamination and biofilm development is played by cell motility and adhesion, that can be heavily dependent on flow conditions.

Mechanics and polarity in cell motility [PDF]
, 2016 The motility of a fish keratocyte on a flat substrate exhibits two distinct regimes: the non-migrating and the migrating one. In both configurations the shape is fixed in time and, when the cell is moving, the velocity is constant in magnitude and ...

FAK-Dependent Cell Motility and Cell Elongation
Cells, 2020 Fibroblastic cells show specific substrate selectivity for typical cell−substrate adhesion. However, focal adhesion kinase (FAK) contributes to controlling the regulation of orientation and polarity.

Bioimage Analysis and Cell Motility
Patterns, 2021 Summary: Bioimage analysis (BIA) has historically helped study how and why cells move; biological experiments evolved in intimate feedback with the most classical image processing techniques because they contribute objectivity and reproducibility to an ...

Stripe formation in bacterial systems with density-suppressed motility [PDF]
, 2012 Engineered bacteria in which motility is reduced by local cell density generate periodic stripes of high and low density when spotted on agar plates. We study theoretically the origin and mechanism of this process in a kinetic model that includes growth ...

Oxidation of F-actin controls the terminal steps of cytokinesis
Nature Communications, 2017 Cytokinetic abscission relies on the local constriction after cytoskeleton disassembly, but it is not known how the actin filaments are disassembled. Here, the authors show that the redox enzyme MICAL1 is recruited by Rab35 and induces oxidation-mediated

Fractional re-distribution among cell motility states during ageing
Communications Biology, 2021 Phillip and colleagues use dermal fibroblasts from a range of donors to quantify cell motility in ageing cells. They show that the age-dependent decrease in cell motility is not due to the reduced motility of all cells, but results from the fractional ...
