A, Quantification of resident macrophages. per collateral section in the absence (occlusion) and presence (occlusion + GTN) of continuous, peripheral GTN infusion (10 μg/h over 72 h) 72 h after femoral artery occlusion, *p < 0.05 vs. occlusion. B, Quantification of proliferation in the absence (occlusion) and presence (occlusion + GTN) of continuous, peripheral GTN infusion (10 μg/h over 72 h) 72 h after femoral artery occlusion, *p < 0.001 vs. occlusion. C, Quantification of collateral-dependent tissue perfusion in the absence (occlusion) and presence (occlusion + GTN) of continuous, peripheral GTN infusion (10 μg/h over 72 h). Ischemic limb perfusion 72 h after femoral artery occlusion was expressed as a ratio of fluorescent microsphere counts in ischemic soleus muscle and related to non-femoral occluded leg (set as 1).
