Abstract

The effect of various growth factors on the synthesis of hyaluronan in human fibroblasts was investigated. When tested in medium containing 0.5% fetal calf serum, platelet-derived growth factor (PDGF)-BB was found to stimulate hyaluronan synthesis; the maximal response was equal to or higher than that obtained with 10% fetal calf serum. PDGF-AA gave only a limited effect, indicating that the stimulatory effect of PDGF on hyaluronan synthesis was mainly transduced via the B-type PDGF receptor. Epidermal growth factor (EGF), basic fibroblast growth factor (bFGF) and transforming growth factor (TGF)-beta 1 also stimulated hyaluronan synthesis; their effects were less than that of PDGF-BB, but combinations of factors produced potent stimulatory effects on hyaluronan synthesis. All factors stimulated hyaluronan synthesis in sparse as well as dense cultures. The effects of the factors on hyaluronan synthesis did not correlate with their mitogenic activities; PDGF-BB, EGF and bFGF are equipotent mitogens, but PDGF-BB had a much more potent effect on hyaluronan synthesis, and TGF-beta actually inhibits the growth of fibroblasts under the conditions of the assay.
