BMP2 and BMP4 stimulate eNOS-dependent PAEC migration. PAECs were stimulated with VEGF, BMP2, or BMP4 with or without l-NAME (100 μm) and assayed for migration using the monolayer wound assay. Data represent the mean ± S.D. (error bars) of three individual experiments. *, p < 0.05 versus serum-starved control; †, p < 0.05 versus corresponding treatment without l-NAME.
