To identify sequences associated with a metastatic pheno‐type, DNA fragments isolated from 2 separate human colon carcinoma metastases were transfected into a mouse bladder carcinoma cell line together with the neo R gene as selectable marker. It was found that bulk populations of neomycin resistant cells carrying these human sequences caused more metastases in syngeneic mice than did control cells transfected with calf thymus DNA. Cells isolated from metastases retained the highly metastases phenotype when transferred to secondary hosts.
