Examples of grafting in the following topics:

  • Skin Grafts

    • Skin grafting is a type of graft surgery involving the transplantation of skin.
    • Skin grafting serves two purposes.
    • The graft is carefully spread on the bare area to be covered.
    • Skin grafting can also be seen as a skin transplant.
    • Skin graft donor site, eight days after the skin was taken

  • Bone Grafting

    • Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures.
    • Most bone grafts are expected to be reabsorbed and replaced as the natural bone heals over a few months' time.
    • As native bone grows, it will generally replace the graft material completely, resulting in a fully-integrated (remodeled) region of new bone.
    • The most common use of bone grafting is in the application of dental implants to restore the edentulous (without teeth) area of a missing tooth.
    • A surgeon places a bone graft into position during a limb salvage.

  • Natural and Artificial Methods of Asexual Reproduction in Plants

    • They include grafting, cutting, layering, and micropropagation.
    • In grafting, two plant species are used: part of the stem of the desirable plant is grafted onto a rooted plant called the stock.
    • The part that is grafted or attached is called the scion .
    • The vascular systems of the two plants grow and fuse, forming a graft.
    • Grafting is widely used in viticulture (grape growing) and the citrus industry.

  • Graft Rejection and Tissue Typing

    • Transplant or graft rejection occurs when a transplanted tissue is rejected by the recipient's immune system.
    • Transplant (or graft) rejection occurs when transplanted tissue is rejected by the recipient's immune system, which destroys the transplanted tissue.
    • Describe the role of tissue typing and graft rejection in transplantation

  • Organ Transplants

    • Tissues capable of transplantation include bones, tendons (both referred to as musculoskeletal grafts), corneas, skin grafts, heart valves, and veins.
    • The cornea and musculoskeletal grafts are among the most commonly transplanted tissues.
    • Regulations include criteria for donor screening and testing as well as strict regulations on the processing and distribution of tissue grafts.

  • Breast Augmentation and Reduction

    • Breast augmentation denotes the breast implant and fat-graft mammoplasty procedures for correcting the defects, and for enhancing the size, form, and feel of a woman's breasts.
    • The fat-transfer approach effects the augmentation, and corrects the contour defects of the breast hemisphere with grafts of autologous adipocyte fat tissue.
    • In non-implant breast augmentation practice, some fat-graft injection approaches feature tissue engineering, which is the pre-operative external tissue expansion of the recipient site.
    • In non-surgical practice, the corrective approaches might consist either of an externally-applied vacuum device, which will expand the tissues of the recipient site, or of oral medications; yet, in most instances, the medium-volume, fat-graft augmentation of the breast is limited to one brassière cup-size, or less.

  • Rhinoplasty

    • The open rhinoplasty approach in turn affords the plastic surgeon the advantages of ease in securing the grafts (skin, cartilage, bone) and, most important, in seeing the nasal cartilages proper, and so make the appropriate diagnosis.
    • Occasionally, the surgeon uses either an autologous cartilage graft or a bone graft, or both, in order to strengthen or to alter the nasal contour(s).
    • The autologous grafts usually are harvested from the nasal septum, but, if it has insufficient cartilage (as can occur in a revision rhinoplasty), then either a costal cartilage graft (from the rib cage) or an auricular cartilage graft (concha from the ear) is harvested from the patient's body.
    • When the rhinoplasty requires a bone graft, it is harvested from either the cranium, the hips, or the rib cage.
    • Moreover, when neither type of autologous graft is available, a synthetic graft (nasal implant) is used to augment the nasal bridge.

  • Major Histocompatibility Complex Antigens (Self-Antigens)

    • However, surgically replaced, or "grafted" organs are very often rejected by the body's immune system.
    • If the T and B cells of the body recognize the HLA of the graft as foreign, they will attack the organ graft.
    • The damage in organ rejection can be acute or chronic, cell-mediated, or antibody mediated, and will often involve diffuse damage of the graft, so far as to cause necrosis and infarction (tissue death from lack of oxygen) to the graft tissue by attacking its vascular components.
    • These drugs are effective at stopping acute organ rejection after the procedure, but will not stop chronic organ rejection, in which gradual vascular lesions and endothelial thickening slowly kills the graft.

  • Purifying Proteins by Affinity Tag

    • Protein tags are peptide sequences genetically grafted onto a recombinant protein.
    • Protein tags are peptide sequences genetically grafted onto a recombinant protein.

  • Noncholera Vibrios

    • Reconstructive surgery, such as skin graft, is indicated in the recovery phase.
