Resveratrol (RSV), as a natural polyphenolic compound, is claimed to be effective in angiogenesis regulation. The aim of</span></span></span></span></span><span style="line-height:150%"><span new="" roman="" style="font-family:" times=""> this study was to evaluate the impact of RSV on angiogenesis process in human umbilical vein endothelial cells (HUVECs) alone and co-cultured with Jurkat cells.<b> </b>The effects of RSV on HUVECs and Jurkat cells viability and apoptosis were measured by MTT and annexin-V/PI methods. HUVECs were co-cultured with pre-treated Jurkat cells and incubated for 24-72 h. Angiogenesis was also investigated by analyzing the expression of</span></span> <span style="line-height:150%"><span new="" roman="" style="font-family:" times="">VEGF, VEGFR-2, and IL-8 employing qPCR and ELISA.<b> </b>Treatment with Jurkat cells had no significant effect on apoptosis of HUVECs at low concentrations of RSV (20-40 µM), but higher concentrations (80-160 µM) increased apoptosis. Although RSV significantly reduced <i>VEGFR2</i> and <i>IL-8</i> gene expression as well as IL-8 protein concentration in HUVECs, this effect was reversed in the Jurkat-treated HUVECs in the co-culture model. The expression of <i>VEGF</i> in Jurkat cells significantly increased following treatment with RSV.<b> </b>Therefore, RSV had a direct antiangiogenic effect on HUVECs. Unexpectedly its indirect effect was not significant on Jurkat-treated HUVECs in co-culture conditions. The results of our experiments highlight that although </span></span><span lang="EN"><span style="line-height:150%"><span new="" roman="" style="font-family:" times="">RSV may be effective in antiangiogenesis therapy, </span></span></span><span style="line-height:150%"><span new="" roman="" style="font-family:" times="">in some conditions it may favor angiogenesis. Therefore, appropriate concentrations should be achieved to minimize the possible unpredicted effects of RSV.</span></span></span></span></span>
