Figure 3From: Microvascular dysfunction in the course of metabolic syndrome induced by high-fat dietEffect of endothelium removal on vasoconstriction responses. A, Mechanical removal of endothelium with a human hair and viability test showing no relaxation response to acetylcholine. B, Endothelium-denuded arteries from both MetS and I-MetS groups still presented significantly increased vasoconstriction responses compared to controls. Data are presented as mean ± SEM, n = 4–5 mice/group, **P <0.01, ***P < 0.001.Back to article page
