Thrombospondin-1 (TSP-1) induces vascular smooth muscle cell (VSMC) migration after arterial injury. TSP-1 up-regulates hyaluronic acid (HyA)-inducing genes in VSMCs. HyA also induces VSMC migration. Our hypothesis was that TSP-1-induced VSMC migration is dependent on the CD44 receptor, and that HyA and TSP-1 share migratory signaling pathways.
