Figure 5: Leukocyte adhesion to human umbilical vein endothelial cells pretreated with Thymelaea microphylla acetone extract (20–40 μg/ml) for 24 h and then exposed to tumor necrosis factor-α (20 ng/ml) for 2 h. A flask containing the co-culture and not exposed to tumor necrosis factor-α was used as control. Increase in leukocyte adhesion upon stimulation of human umbilical vein endothelial cells with tumor necrosis factor-α was calculated in relation to the basal adhesion of leukocytes to nonstimulated human umbilical vein endothelial cells (that was set to 1). Data are reported as mean ± standard deviation of three experiments. *P < 0.05 versus respective tumor necrosis factor-α 0 ng/ml; §P < 0.05 versus vehicle exposed to tumor necrosis factor-α 20 ng/ml
