Fig. 7From: Regular transient limb ischemia improves endothelial function and inhibits endothelial cell apoptosis to prevent atherosclerosis in rabbitIdentification of aortic endothelial cells. (A) Typical micrograph of isolated aortic endothelial cells was observed under an inverted microscope (×100). (B) Representative image of endothelial cells by CD31 immunofluorescence staining was obtained under an inverted fluorescence microscope (×200). Cells nucleus are stained by DAPI (blue). CD31 positive cells exhibit green fluorescence. Above 95% of the cells are expressed CD31 positiveBack to article page
