Tissue or an organ that is transplanted from one part of the body to another or from one individual to another. Grafts can be autografts (from the same person), allografts (from another person), or xenografts (from another species).
From Old French 'graffe' meaning a stylus or pencil, later applied to plant grafting where a shoot is inserted into another plant. The medical use developed in the 19th century when surgeons began transplanting tissues using similar insertion techniques.
