TNF and Hyperglycemia: We studied the effects of TRAIL (100 ng/ml) on human aortic endothelial cells (HAECs) exposed to pro‐atherogenic conditions; (a) oscillatory shear stress (±10 dynes/cm2) using the ibidi μ‐slide fluidic system; (b) pro‐inflammatory injury, that is, tumor necrosis factor alpha (TNF‐α, 100 ng/ml) and hyperglycemia (30 mM d‐glucose).
