• ALL MET-1 (100%) ANIMALS HAD PULMONARY METASTASES BY 50 DAYS.
• SOME (8.8%) Db-7 MICE DEVELOPED METASTASES.
• NO LONG-TERM Db-7 SURVIVORS HAD METASTASES.
• THUS, MET-1 TUMORS ARE HIGHLY METASTATIC WHILE THE Db-7 TUMORS HAVE A LOWER METASTATIC POTENTIAL.
• TRANSPLANTED PULMONARY TUMORS FROM BOTH Db-7 (pD) AND THE MET-1 (pMET) WERE HIGHLY METASTATIC.
