In the field of medical research, grafts refer to the process of transferring tissues or organs from one part of the body to another or from one individual to another. This can include skin grafts, bone grafts, organ transplants, and tissue transplants. Grafting is commonly used in surgeries to repair and reconstruct damaged or missing tissues, improve function, and promote healing. Researchers are constantly working to improve the success rates and outcomes of grafts through advancements in surgical techniques, immunosuppressive therapies, and tissue engineering.
