Endothelium-independent vasodilation to nitroprusside was less pronounced in mesenteric arteries of Ossabaw minipigs than of Göttingen minipigs. Data are presented as means ± SD. The means ± SD were calculated from averages of 1–3 vessels per pig, respectively; 87 vessels of n = 38 Göttingen minipigs and 58 vessels of n = 27 Ossabaw minipigs. A and B: two-way analysis of variance for repeated measures: #P < 0.001 Göttingen minipigs vs. Ossabaw minipigs, Fisher’s least significant difference post hoc test. *P < 0.05 vs. Göttingen minipigs.
