Objective:To gain purified recombination protein rGPI-vWF A3 which can guide endothelial progenitor cells (EPCs) gathering to the internal surface of the injured vessels theoretically and analyze its bioactivity in vitro. Methods: The plasmid vector of vWF A3 fusion protein which contained GPI structure was constructed and recombination protein rGPI-vWF A3 was expressed and its bioactivity was analyzed by ELISA and FCM. Results: Fusion protein vWF A3-GPI was expressed and purified by immunoaffinity chromatography and it could stably anchored on the surface of EPCs and showed its biological activities of collagen conjunction. Conclusion: These findings represent a novel strategy in EPC transplantation treatment for vessel injury.
