YRGDS is a synthetic peptide sequence that mimics the cell-binding domain of fibronectin, a key protein involved in cell adhesion and migration. It is primarily used in biomedical research and tissue engineering to enhance cell attachment to biomaterial surfaces. By incorporating YRGDS into scaffolds or coatings, researchers can improve the integration of synthetic materials with living tissues, making it valuable in the development of implants and regenerative medicine strategies. The sequence helps direct cellular behavior, such as spreading and proliferation, especially in studies involving stem cells or wound healing. Its application is also explored in drug delivery systems where controlled cell interaction is required.
