The invention provides methods, compositions, and devices for promoting adhesion or migration of endothelial cells.
1. An implantable medical device comprising a fragment of human tropoelastin, a biocompatible polymer selected from the group consisting of plastic, silicone, dacron, polyurethane, polypropylene and polytetrafluoroethylene (PTFE), and an anti-CD34 antibody, wherein the human tropoelastin fragment consists of the amino acid sequence of SEQ ID NO: 6, and wherein said device is coated with said fragment.
2. The device of claim 1 , wherein said device comprises a metal, an alloy or a plastic.
3. The device of claim 2 , wherein the metal comprises stainless steel.
4. The device of claim 1 , wherein said device is selected from a catheter, stent, shunt, wire, and other intraluminal device.
5. The device of claim 1 , wherein said device is selected from a stent, a pacemaker, cardioverter-defibrillator, artificial valve, and vascular graft.
6. The device of claim 1 , wherein the antibody is monoclonal.
7. The device of claim 1 , wherein the amount of the fragment of human tropoelastin is at least 100 ng per square centimeter.
