BMP9 and BMP10 regulated genes in endothelial cells. mRNA fold changes in Dll4, Jag1, Hey1, Hey 2, Hes1, and apelin mRNA levels in hPAEcs stimulated with 0.5 ng/mL BMP9 or BMP10 at different time points (1, 2, 4, and 6 hours). Expression of HPRT was used as the normalization control. Data pooled from 3 individual experiments, each containing 2 replicates. Error bars show SEM.
