Figure 1

Effects of VEGF ₁₅ , VEGF ₁₆₅ and QK on the vasomotor responses of 12 common carotid arteries from normotensive rats (A). Both VEGF₁₆₅ and QK induced a comparable vasorelaxation, while VEGF₁₅, has no evident effect. After removal of the endothelial layer there is no appreciable vasorelaxation (B). * = p < 0.05 vs VEGF₁₅. Error bars show SEM.
