The conditions affecting the appearance and disappearance of platelet-derived growth factor (PDGF) receptors from the pool of active cell surface-associated receptors were studied. Receptor molecules were revealed in intact Swiss 3T3 fibroblasts by their ability to bind 125I-labeled PDGF and, due to their property to become phosphorylated in tyrosine following ligand binding, by antibodies to phosphotyrosine. PDGF receptor molecules were found to be quite scarce in exponentially growing fibroblasts as compared to quiescent cells. When growing cells were either shifted to a medium containing plasma or received suramin in the culture medium, cell surface-associated PDGF receptors largely increased. This process required about 12 h. Incubation of quiescent cells in serum, but not in plasma, induced a slow decrement of ligand-activatable receptors. In the presence of PDGF the rate of receptor removal from the cell surface was very rapid and was a function of the PDGF concentration. Quiescent cells deprived of cell-surface receptors by incubation with PDGF reexpressed PDGF receptors in about 14 h.
