AGENTS AND DEVICES FOR USE IN PREVENTION OF RESTENOSIS
Agents that inhibit or prevent restenosis are identified by assaying test agents in a battery of assays to measure the effect of the test agent on cell proliferation, thrombosis, tissue modeling, and inflammation. Treatment for restenosis is provided using compositions of the invention.
