BMP2 and BMP4 stimulate eNOS phosphorylation in PAECs. A and B, representative Western blots of bPAECs stimulated with BMP2 (A) or BMP4 (B) for various times and analyzed for eNOS phosphorylation at serine 1179. VEGF was used as a positive control. C, results of densitometric analysis of Western blots from four individual experiments. Data show the -fold change in eNOS phosphorylation and are the mean ± S.D. (error bars).
