Tissue engineering is a multidisciplinary field that involves the development of biological substitutes to restore, maintain, or improve the function of damaged or diseased tissues and organs. It combines principles from engineering, biology, and medicine to create artificial tissues and organs that can be implanted in the body to replace damaged or diseased tissues. Tissue engineering holds great promise for a variety of medical applications, such as regenerating damaged heart tissue after a heart attack, repairing cartilage in arthritic joints, or creating artificial skin for burn victims. Researchers in tissue engineering work to develop techniques for growing cells, engineering biomaterials, and designing scaffolds that support tissue growth and function.
