Late-passage cells of a nontumorigenic and anchorage-dependent hepatic epithelial line (WB-F344), which produce insulinlike growth factor II and transforming growth factor β constitutively, grow in serum-free medium supplemented only with transferrin. In the presence of transferrin, epidermal growth factor further augments population growth, although epidermal growth factor alone is without effect. Insulin, platelet-derived growth factor, and several inorganic iron salts are also ineffective in supporting cell growth in the absence of transferrin; furthermore, these factors do not augment the action of transferrin. The population growth-promoting effect of transferrin occurs at concentrations of 0.5 nM or greater and the maximal effect is reached with a concentration of approximately 6 nM. A lipophilic iron chelator, ferric pyridoxal isonicotinoyl hydrazone (FePIH), can fully mimic the effect of transferrin on the proliferation of WB-F344 cells, but the molar concentration of FePIH required to promote cell proliferation is 1000-fold higher than the molar concentration of transferrin. These results suggest that the critical function of transferrin in the proliferation of WB-F344 cells may be in the delivery of iron to the cells. In the absence of transferrin the proliferation of WB-F344 cells is arrested in serum-free medium in the G 0 G 1 phase, and a period of protein synthesis after the addition of transferrin is necessary before the cells can proceed to S phase and initiate DNA synthesis. Replacement of transferrin causes quiescent WB-F344 cells to cycle parasynchronously. Epidermal growth factor does not alter the length of the latency period prior to S phase but appears to stimulate the uptake of [3 H] thymidine subsequently. Transferrin may act as a “competence” and/or “progression” factor, allowing the replication of these epithelial cells in vitro.
