Background: Vascular smooth muscle cell (VSMC) migration is a critical process in arterial
remodeling. Purified plasminogen activator inhibitor‐1 (PAI‐1) is reported to both promote
and inhibit VSMC migration on two‐dimensional (D) surfaces. Objective: To determine the
effects of PAI‐1 and vitronectin (VN) expressed by VSMC themselves on migration through
physiological collagen matrices. Methods: We studied migration of wild‐type (WT), PAI‐1‐
deficient, VN‐deficient, PAI‐1/VN doubly‐deficient (DKO) and PAI‐1‐transgenic (Tg) VSMC …
