2 Fig. 1 PAI-1 levels in aortic tissue-explant supernatants increased over time. PAI-1 levels increased over time in all seven samples. PAI-1 levels in the three aneurysmal specimens (circles) continued to rise over the entire 72-hour period. In contrast, PAI-1 levels in four normal tissue samples (squares) rapidly increased until approximately 24 hours and then remained relatively constant.

3 Fig. 2 PAI-1 Northern blot analysis and 2.3-kb species of PAI-1 mRNA migrate between the 28S and 18S ribosomal bands. Notice the decreased signal of GAPDH in diseased aorta, indicating uneven loading of RNA (N, normal samples; A, aneurysms; O, occlusive samples; E and H are endothelial cell and Hep G2 tissue culture RNA used as positive control samples, respectively).

4 Fig. 3 PAI-1 in-situ hybridization. A, In this aortic arteriole, PAI-1 mRNA localizes to endothelial cells of vasa vasorum (arrow). Original magnification, 40×. B, Sense PAI-1 probes, used as negative control sample, revealed no binding to endothelial cell vasa vasorum. Original magnification, 40×. C, Vascular SMC positive for PAI-1 mRNA. Original magnifacation, 100×. D, Section of aneurysm shows positive lumenal endothelial cells (solid arrow) and scattered positive intimal cells (open arrow).
