The field of regenerative medicine is a branch of medical research that focuses on developing methods to restore damaged or lost tissues and organs in the body. This can be achieved through various techniques, including cell therapy, gene therapy, and tissue engineering, with the goal of improving patients' quality of life and treating diseases and injuries more effectively. Regenerative medicine aims to promote healing by stimulating the body's natural ability to regrow damaged or lost cells and tissues, rather than just managing symptoms or replacing damaged parts with artificial devices.
