From: Vasomotion of mice mesenteric arteries during low oxygen levels
Comparison of vasomotion at moderate and severe hypoxic conditions. The results are shown as percentage changes in relation to the initial diameter under normoxic conditions. The X-axis represents the investigated groups, wt-co.: wild-type controls, Ca2+-free: Ca2+-free Tyrode’s solution, NiCl2: Tyrode’s solution containing 2.5 mM NiCl2. a Vasomotion under 12.2% oxygen; b vasomotion under 2.7% oxygen; negative algebraic sign on the Y-axis: constriction of the arterial segment; (*p < 0.05; **p < 0.01; Mann–Whitney U test for non-parametric data)
