Sources of proliferating cells in coronary thrombus. Representative images of cells undergoing proliferation in coronary thrombus (top to bottom): macrophages (A-D), smooth muscle cells/SMC (E-H), and endothelial cells (I-L). Boxed areas in HE stains (A, E, I) show the areas of interest for higher magnification of double immunostaining Ki67 (C, G, K) antibodies with cell specific antibodies: anti- CD68 (B), αSMA (F) and CD34 (J), as well as of false-colour images to show co-localization of the positive cells (in red) with Ki67⁺ (in green) as proliferating cells (D, H and L, in yellow). Scale bar in HE overviews (A and I): 100 µm and in high power detail (B and F): 25 µm.
