contact inhibition of movement

contact inhibition of movement
Reaction in which the direction of motion of a cell is altered following collision with another cell. In heterologous contacts both cell may respond (mutual inhibition), or only one (non-reciprocal). Type I contact inhibition involves paralysis of the locomotory machinery, Type II is a consequence of adhesive preference for the substratum rather than the dorsal surface of the other cell.
