Fig. 7From: Characterization of atherosclerotic plaques in blood vessels with low oxygenated blood and blood pressure (Pulmonary trunk): role of growth differentiation factor-15 (GDF-15)Exemplary post-mortem human necropsy of atherosclerotic pulmonary artery: A HE, B sm-α-actin+, (smooth muscle); C CD68+ (macrophages); D TUNEL (apoptosis); E Ki67 (proliferation), F APG5L/ATG (autophagy) and G negative control (absence of the primary antibody). Cell nuclei were counterstained with hematoxylin. L: Lumen, Nc: Necrotic core, Tm: Tunica media.
