"[Cells transfected with DNA from the malignant human breast carcinoma cell line, Ca2-83, or DNA from the human pleural effusion-derived cell lines, MCF-7 or ZR-75-1, yield transformants which metastasize to lungs and/or lymph nodes at high frequency, whereas transfection of HindIII-fragmented DNA from nonmetastatic human mammary epithelial cell lines, transfection of the drug-resistance plasmid pSV2neo alone, or nonspecific DNA such as salmon sperm DNA fails to yield transformants expressing the metastatic phenotype.].
