Cell migration involves formation of a leading edge in the direction of migration and adhesion points from which tension is generated to move the cell body forward.
Topography affects the growth direction of processes and the adhesion of astrocytes.
Altering the balance of adhesion strength in either direction (causing weaker or stronger adhesions) disrupts the migration of model cells in vitro [22], [66].
Simplified, by changing the direction of loading, either the normal adhesion force is high and the friction is low, or the frictional component is high and the normal adhesion force is low.
Resulting structures were further tested to find the influence of laser processing on the interaction of created scaffolds with the living cells in the direction of improvement of their directional growth and adhesion.
Additionally, the shear strengthening of FimH in E. coli supports the implications for the possibility of direction-dependent adhesion mechanisms in bacteria, similar to those suggested for mammalian cells (Isabey et al. 2013).
The location and direction of the point of where the maximum shear stress is located with respect to the direction of the applied load varies with the level of adhesion.
Local balance between myosin II-mediated contractile forces, adhesive interaction of cells with neighboring cells, and the generation of traction in the direction of lamellipodia extension contribute to growth, adhesion strengthening, and disruption of radial AJs.
Changes in expression of other genes, though not always statistically significant, show the same direction of extract activity, lowering migration, and adhesion of leukocytes (MCP1 and ICAM1).
Mr. Haywood, who had a reputation for keeping Porsches pointed in the right direction, said the trick was to drive the car right to the limits of adhesion, but not beyond.
