Expression ratios of VSMCs to CCL22

The expression levels of VSMCs and CCL22 were quantified as positive areas by Photoshop CS (Adobe Systems Incorporated, San Jose, CA). A. and B. show the positive area ratios of VSMCs/CCL22 of high and low VSMC density areas in a human common carotid artery (Fig. 1) and human coronary artery with a bare metal stent (Fig. 2). The measurements were performed independently by three pathologists. A significant negative correlation between the expression levels of VSMCs and CCL22 was found. Values represent the mean ± SD of triplicate measurements from three independent experiments (***P < 0.001).
