RGD peptide (GRGDNP) is widely used in biomedical research and applications due to its ability to promote cell adhesion. It is commonly incorporated into biomaterials, such as hydrogels, scaffolds, and coatings, to enhance cell attachment and growth. This makes it valuable in tissue engineering for regenerating bone, cartilage, and other tissues. In drug delivery systems, RGD peptide is used to target specific cells, such as cancer cells, improving the precision of therapeutic agents. It also plays a role in studying cell signaling pathways and interactions with extracellular matrix components. Additionally, RGD peptide is utilized in diagnostic imaging to visualize tumors and other diseased tissues. Its versatility in promoting cell-specific interactions makes it a key tool in advancing medical and biological research.
