Abstract. DA FARE! 1. Introduction. Cells that move through tissues (like cancer metastases, or fi-broblasts) interact with the tissue matrix (the Extra-Cellular Matrix, usually short-ened as ECM) as well as with other cells. Recently, much attention has been devoted to the description of the mechanicsms of motions of cells as a result of their interac-tion with the ECM. A detailed description of the physiological mechanisms is give
