Cell motility is a fascinating example of cell behavior which is fundamentally important to a number of biological and pathological processes. It is based on a complex self-organized mechano-chemical machine consisting of cytoskeletal filaments and molecular motors. This network is highly dynamic, but able to show precise spatial and temporal organization. The machine is regulated by a complex network of biochemical reactions coupled to force and movement generating processes.

In general, the cytoskeleton is responsible for the movement of the entire cell and for movements within...
