Acetylcholine-depended endothelium-mediated vascular relaxation of isolated aortic rings of Adipoq-/- mice, aortic rings of Mpo-/- mice incubated with Adipoq-/- PVAT (Mpo-/-PVATAdipoq-/-) vice versa, and respective controls. For (L), significances are shown for Mpo-/-PVATAdipoq-/- vs. Adipoq-/-PVATMpo-/-: *p< 0.05. n= as indicated.
