two mechanisms concerning the noninvasiveness of mcf-7 cells in vitro are discussed : the homotypic adhesion of the mcf-7 cell population due to the presence of numerous desmosomes , and the incapability of mcf-7 cells to migrate on extracellular laminin present in the embryonic chick heart and in the hbl-100 cell population .
