Resumen

A Chinese hamster ovary cell line that stably expresses transfected human platelet-derived growth factor (PDGF) A and B chain precursors was established. All three dimeric combinations of PDGF chains were produced by this cell line; their biosynthesis, assembly, and processing were followed by pulse-chase analyses. PDGF-AA, PDGF-AB, and PDGF-BB were processed to M(r) values of about 30,000 and were accumulated in these forms in the medium. In addition, PDGF-BB was further processed to a 24-kDa component, which remained cell-associated. The major secreted component was PDGF-AB, which was purified and shown to have structural and functional characteristics indistinguishable from PDGF-AB purified from human platelets.
