in order to study the effect of estrogens and antiestrogens on the adhesive properties of human breast cancer cells , the attachment on endothelial cells ( ec ) , on subendothelial extracellular matrix ( ecm ) and on ecm components ( collagen i and iv , laminin , fibronectin ) of estrogen-dependent ( mcf-7 , zr75-1 ) and estrogen-independent ( bt-20 ) breast cancer cell lines was investigated .
