Integrin signalling in directed cell migration.
Migrating cells tend to continue moving in the same direction, a property called persistence. During migration, cells, by definition, form new adhesions at their front and break old adhesions at the rear. We hypothesize that the distinction between new adhesions at the front and older adhesions at the rear plays a major role in directional persistence. We propose specific mechanisms of persistence on the basis of known properties of integrin signals, in hope of stimulating investigation of these ideas.
