Stability and bioactivity of pepCD47 attachment on stainless steel surfaces.

ABSTRACT: In-stent restenosis (ISR) and late stent thrombosis are the major complications associated with the use of metal stents and drug eluting stents respectively. Our lab previously investigated the use of peptide CD47 in improving biocompatibility of bare metal stents in a rat carotid stent model and our results demonstrated a significant reduction in platelet deposition and ISR. However, this study did not characterize the stability of the pepCD47 on metal surfaces post storage, sterilization and deployment. Thus, the objective of the present study was 1) to test the stability of the peptide post - storage, sterilization, exposure to shear and mechanical stress and 2) to begin to expand our current knowledge of pepCD47 coated metal surfaces into the preclinical large animal rabbit model.
