in the present study , clonal cell lines of transformed highly tumorigenic and metastatic ( t-ref-g-1.1 ) , weakly tumorigenic and nonmetastatic ( t-ref-g-2.1 ) , nontumorigenic ( t-ref-g-2.0 ) , and secondary nontransformed rat embryo fibroblast cells were labeled with [ 3h ] fucose , and cell extracts were analyzed for ratio of radioactivity incorporated into fl3 and fl4 .
