【Abstract】 RGD is connected onto the surface of biomaterials, and followed by cultivating endothelial cell, which is one of the best ways in improving the blood comparability of cardiovascular materials.The tripeptide RGD is synthesized by the method of liquid synthesis. The bioactive of the tripeptide RGD has been investigated. The preliminary result shows that the tripeptide RGD possesses the ability to promote the attachment between materials and endothelial cell.更多还原
