Figure 3From: An experimental study of VEGF induced changes in vasoactivity in pig retinal arterioles and the influence of an anti-VEGF agent Concentration response curve of VEGF from ET-1 pre-contracted retinal arterioles. In isolated pig retinal arterioles pre-contracted with ET-1 (3 x 10-9 M) VEGF exhibited a concentration dependent vasodilatation response. * Denotes a significant dilatation compared to contracted baseline (p < 0.05).Back to article page
