title: Growth factor requirements of oncogene-transformed NIH 3T3 and BALB/c 3T3 cells cultured in defined media.
abstract: We report conditions for the efficient growth of NIH 3T3 and BALB/c 3T3 cells cultured in a defined medium supplemented with either platelet-derived growth factor (PDGF) or pituitary-derived fibroblast growth factor (FGF). The oncogenes v-mos, v-src, v-sis, and c-H-ras Val 12 can induce morphological transformation of these cells and can release them from the mitogen requirement for growth, while the oncogene v-fos cannot abrogate the PDGF-FGF requirement. The radically different behavior of normal and transformed NIH 3T3 cells in PDGF-FGF-free defined medium can form the basis of a sensitive new fibroblast transformation assay.
