The motility of living eukaryotic cells is a complex process driven mainly by polymerization and depolymerization of actin filaments underneath the plasmatic membrane (actin cytoskeleton). However, the exact mechanisms through which cells are able to control and employ ‘actin-generated’ mechanical forces, in order to change shape and move in a well ...

Actin-dependent motile forces and cell motility
Current Opinion in Cell Biology, 1994Force arising from actin polymerization and myosin activity drives a number of different actin-based cell movements. Several new reports support previous data suggesting that actin polymerization drives lamellipodial protrusion and bacterial propulsion, and one report describes a more indirect role for actin assembly in axonal elongation. The major new

Contraction-Driven Cell Motility
Physical Review Letters, 2013We propose a mechanism for the initiation of cell motility that is based on myosin-induced contraction and does not require actin polymerization. The translocation of a cell is induced by symmetry breaking of the motor-driven flow, and the ensuing asymmetry gives rise to a steady motion of the center of mass of a cell.

Cell migration is required during development of the nervous system. The regulatory mechanisms for this process, however, are poorly elucidated. We show here that expression of or exposure to the neural cell adhesion molecule (NCAM) strongly affected the motile behaviour of glioma cells independently of homophilic NCAM interactions.Expression of the ...

This report summarises practical aspects to measuring cell motility in culture. The methods described here were discussed at a 1-day European Tissue Culture Society (ETCS-UK) workshop organised by John Masters and Gareth E Jones that was held at University College London on 19th April 2007.

Mathematical Models of Cell Motility
Cell Biochemistry and Biophysics, 2007Cell motility is an essential biological action in the creation, operation and maintenance of our bodies. Developing mathematical models elucidating cell motility will greatly advance our understanding of this fundamental biological process. With accurate models it is possible to explore many permutations of the same event and concisely investigate ...

Cell motility in fibroblast aggregates
Journal of Cell Science, 1978ABSTRACT The stable arrangements of cells in tissues and organs require that most tissue cells, whatever their inherent abilities for active pseudopod-directed locomotion, remain confined to the boundaries of their parent tissues and organs for the lifetime of the organism.

Many specific endothelial cell functions in vivo, such as control of vessel wall permeability or non-thrombogenicity, require continuity of the endothelial cell monolayer (17). Endothelial cell motility is one of several mechanisms which secure the integrity of the vascular intima during physiologic replacement of endothelial cells and provide rapid ...

Surgery, chemotherapy and radiotherapy are the current modalities of tumor management. However, in systemic disease, predicted patients’ cure can be achieved in but a few tumor diseases. Based on previous basic research we have highlighted that the loss of cell-cell adhesion in association with an increased tumor cell motility is an essential feature ...
