Distribution of HMGB1+ cells and Correlation of Ki67 with HMGB1.

<p>Ki67 expression in stented swine coronary artery with an injury score greater than 2 (A-C) shows the concentration of Ki67+ cells around the stent struts (A-C) and the corresponding Movat’s pentachrome stain showing the fragmented IEL and inflamed stent strut (D). HMGB1 expression in cells surrounding the stent struts (E-G) in stented swine coronary artery with an injury score greater than 2 shows that some cells around the stent struts express both HMGB1 and Ki67. HMGB1 expression in smooth muscle cells (I-K) in stented swine coronary artery with an injury score greater than 2 demonstrates the location of the positive smooth muscle cells in relation to the fragmented IEL (L). These are representative histological slides from N = 3 in each injury score group.
