Exploration of cell-type expression of AOC3 during the development and progression of murine and human atherosclerosis was performed by co-immunofluorescent staining between AOC3 and α-SMA (Supplementary Figure 5A), CD31 (Supplementary Figure 5B), and MOMA-2 (Supplementary Figure 5C). This evidence concerns the gene PECAM1 and atherosclerosis.
