v. grafted, grafting, grafts
To transplant or implant (living tissue, for example) surgically into a bodily part to replace a damaged part or compensate for a defect.
1. To make a graft.
2. To be or become joined.
a. Material, especially living tissue or an organ, surgically attached to or inserted into a bodily part to replace a damaged part or compensate for a defect.
b. The procedure of implanting or transplanting such material.
c. The configuration or condition resulting from such a procedure.
graftImmunology Any tissue taken from one part of the body of the same or different person and used to replace diseased or injured tissue in another part of the body. See Allograft, Bone graft, Bypass graft, Corneal graft, Coronary artery bypass graft, Dermagraft, Endovascular stent graft, Endoscopic coronary artery bypass graft, Fetal brain graft, Hair graft, Hemi-homograft, Hemobahn endovascular graft, Irradiated chondral graft, Isograft, Micrograft, Minigraft, Skin graft, Split thickness graft, Standard hair graft, Strip graft, Test graft, Tissue graft, White graft.
1. Any free (unattached) tissue or organ for transplantation.
graftA tissue or organ, taken from another part of the body or from another donor person, and surgically implanted to make up a deficit or to replace a defective part. To be successfully retained, a graft must quickly establish an adequate blood supply and must be able to resist immunological rejection responses.
graftthe transfer of a small part of an organism to a relatively larger part where it is transplanted. This may take place from one part of an organism to another part (see AUTOGRAFT), or from one organism to another (see ISOGRAFT, HOMOGRAFT, HETEROGRAFT). Many embryological studies have involved grafting, and from a medical point of view, skin grafting, particularly after serious burns, is commonplace. Organ grafts such as heart transplants are now much more common, though rejection by an animal of the tissues of another is still a serious problem (see IMMUNE RESPONSE). In animals the graft comes from a ‘donor’ and is transferred to the recipient. In plants, grafts are used often in horticulture, where a scion, the plant to be cultivated, is attached onto a STOCK (1), the rooting portion.
To implant living tissue surgically. In coronary artery bypass graft surgery, healthy veins or arteries are grafted to coronary arteries.
1. Any free (unattached) tissue or organ for transplantation.
