Infiltrating cells of the intima in coronary and carotid plaques are CD100 positive.

CD100 labeling (E-H) and negative controls (A-D) in artery tissue sections of carotid plaques (A, B, E, F) and coronary plaques (C, D, G, H) by immunohistochemistry. Positive CD100 staining was observed only in preserved endothelium (arrowhead), and in infiltrating cells in the intima (asterisks). Scale bars: 10µm (A, E, C and G), and 50µm (B, F, D and H).
