Abstract

The sequences of surface adsorption of fibrinogen (Fgn) responsible for phagocyte attraction and adhesion were examined using plasmin-generated Fgn fragments. Polyethylene terephthalate (PET) disks were cut and sterilized in ethanol. Protein coating was achieved by incubating hydrated PET disks with solutions of albumin, Fgn, Fgn fragments, peptide-linked albumin or saline at room temperature for 16 hours under sterile conditions. Samples of PET were implanted in Swiss Webster mice to serve as an in vivo model for assessing inflammatory cell responses to biomaterials. Experimental results suggest that the interactions between the Fgn and macrophage are important in the accumulation of phagocytes on implant surfaces and early inflammatory responses.
