Proliferation of hRMVECs in the presence of 2–16 ng/ml of VEGF (left bars).

<p>Right 3 bars represent proliferation of hRMVECs treated with 1000-fold dilutions of spent media from D407 cells exposed to (i) normoxia/Nor, (ii) hypoxia/Hyp, and (iii) hypoxia treated with 20 µM honokiol/Hyp+Hon. Each error bar represents the standard deviation calculated from six experimental replicates.</p>
