Chemotaxis, the process by which cells move towards soluble factors, is one of the most fascinating areas of modern biology. For cells to migrate up an attractant gradient they must detect signals, ...

In this paper, we derive the conditions for the existence of stationary solutions (i.e., nonconstant steady states) of a volume-filling chemotaxis model with logistic growth over a bounded domain ...

The intricate mechanisms that allow certain cells to move have been uncovered by researchers, discoveries with implications for cancer metastasis, say authors of a new report. What if cancer cells ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 94, No. 21 (Oct. 14, 1997), pp. 11577-11582 (6 pages) Divalent cations are thought essential for motile function ...

Chicken soup was found to inhibit neutrophil chemotaxis. When the completed soup (without added salt and pepper) was added to neutrophils above the membrane, to the ZAS below the membrane, or to both ...

Agent-based simulation of 1,080 cells in a 3D medium with a vertical aspartate gradient, shown at 54, 150, and 400 seconds after simulation start. 540 cells are sensitive to aspartate (green) and 540 ...

An all-on-chip method enables rapid neutrophil chemotaxis assay directly from a few microliters of blood for both cell migration research and clinical sample test. A team of researchers from the ...

Chemokines are a large subfamily of small cell signaling proteins or cytokines, which in conjunction with their G protein-coupled receptors (GPCR), govern the process of cell migration. The role of ...
