Beschreibung
Zusammenfassung:	Provided are a pro-endothelialization biological material and method for preparation thereof, and a pro-endothelialization heart valve and method for preparation thereof and interventional system. The pro-endothelialization biological material comprises a biological material and a pro-endothelializing growth factor loaded on the surface of biological material; capable of capturing endothelial progenitor cells, enabling the endothelial progenitor cells to attach, grow, and differentiate on the surface of the biological material. The methods for preparation of the pro-endothelialization biological material comprises chemical grafting and physical coating methods. The heart valve can be prepared either by suturing followed by grafting or by grafting followed by suturing. A endothelial growth factor is directly loaded onto the surface of a biological material film, promoting the formation of endothelial cell layers on the surface of the biological material.
