Objective:To construct SDF-1&Fucoidan bio-coatings to reduce restenosis and later thrombosis existing in implants materials application. Methods:The materials surface was firstly treated with APTE solution to form active amino-group;subsequently SDF-1 and Fucoidan were immobilized by a simply co-immobilization with EDC/NHS coupling agent. Various materials characterization and bio-compatibility evaluation were employed. Results:XPS results showed that SDF-1 and Fucoidan have been successfully grafted on materials surface. SEM image and statistics proved that platelet adhesion on SDF-1 & Fucoidan coatings was decreased and the activation was lowed. In particular
the optimal grafted Fucoidan concentration of the complex coating was about 100 μg/ml. Furthermore
endothelial progenitor cells(EPCs) culture experiment revealed the coating would promote EPCs adhesion and proliferation obviously;the optimal concentrations of SDF-1 and Fucoidan were respectively 80 ng/ml and 100 μg/ml. Conclusion:SDF-1 &Fucoidan complex coating displays excellent anti-coagulant
