Figure Lengend Snippet: Transmission electron microscopy of carotid arteries of WT and PAI-1−/− mice 3 days after cuff implantation. A: A neutrophil with vesicular transport activity (arrow) is seen attached to the luminal endothelium in WT carotid artery close to a cellular junction (asterisk) (original magnification, ×11,500). B: A polymorphonuclear leukocyte (arrow) is present in an open subendothelial space in WT carotid artery (original magnification, ×6,200). A and B suggest that a diapedesis process is occurring. C: Altered cellular morphology of an endothelial cell (E) is evident in PAI-1−/− carotid artery, the result of copper-induced injury (original magnification, ×6,800). D: Activated macrophages with visible phagolysosomes (P) are evident in the medial compartment of a PAI-1−/− carotid artery (original magnification, ×2,700).

Figure Lengend Snippet: Histological analysis of carotid arteries from WT and PAI-1−/− mice 7 days after implantation of the copper cuff. A: H&E stain of WT carotid artery demonstrates a reactive adventitial (asterisk) and medial (arrow) compartments with the presence of a small neointima (arrowhead). Original magnification, ×200. Similar H&E staining of a carotid artery from a PAI-1−/− mouse (B) shows a quiescent state of these vascular compartments. Original magnification, ×200. C: Anti-α-actin immunostain of a WT carotid artery demonstrates enhanced smooth muscle cells in the medial compartment (arrow) (original magnification, ×200), whereas a PAI-1−/− carotid artery (D) indicates no apparent change in the smooth muscle cell population in the medial compartment. Original magnification, ×200. E: CD45 immunostain of WT carotid artery demonstrates a leukocyte-enriched adventitia (arrow). Original magnification, ×200. F: CD45 immunostain of WT carotid artery demonstrates leukocytes within the neointima (arrow). Original magnification, ×400. G: Anti-fibrin(ogen) immunostain of WT carotid artery shows fibrin-rich medial (arrow) and adventitial (asterisk) compartments (original magnification, ×200), whereas similar immunostaining of a PAI-1−/− carotid artery (H) demonstrates no apparent fibrin deposition in the vessel wall. Original magnification, ×200.
