Fig. 7. Inhibition of PDGF- or bFGF-stimulated SMC proliferation by antibodies against UPA and p-aminobenzamidine. Cell counts [medians (IQR) of 3-4 independent experiments] were performed over periods of 7 days on PDGF- (A) or bFGF- (B) stimulated SMC cultured in the absence (hexagon) or in the presence of 40 µg/ml polyclonal goat anti-UPA 398 ([UNK]), 40 µg/ml monoclonal mouse anti-UPA 394OA (), or 250 µM of the UPA inhibitor p-aminobenzamidine ().
