COMP-Ang-1 gene transfer attenuates the microvascular rarefaction and tissue ischaemia in the heart and kidney of SHRs. The microvasculature of the heart (A) [arrowheads in (A) indicate the

absence of capillaries], (B) and kidney (C) was visualized and quantified by immunohistochemical staining with CD31 IgG on frozen sections or RECA IgG on paraffin

sections, respectively.
