Allotransplant (allo-meaning "other" in Greek) is the transplantation of cells, tissues, or organs to a recipient from a genetically non-identical donor of the same species. [1] The transplant is called an allograft, allogeneic transplant, or homograft. Most human tissue and organ transplants are allografts.
Allotransplantation (homogenous), where a tooth is transferred from one individual to a different individual of the same species. [1] Nowadays, it is largely abandoned as the practice carries many risks including transmission of infection, such as syphilis , [ 2 ] and histocompatibility issues. [ 3 ]
Allotransplantation refers to tissue transplant between individuals with different genetic makeup. [10] [11] Although the genetic composition variation in allografts is not as large as that in xenografts, the rejection rate remains high. To minimize rejection, cautious donor-recipient matching is needed.
Nerve allotransplantation (allo- means "other" in Greek) is the transplantation of a nerve to a receiver from a donor of the same species. For example, nerve tissue is transplanted from one person to another. Allotransplantation is a commonly used type of transplantation of which nerve repair is one specific aspect.
Organ transplantation is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ. The donor and recipient may be at the same location, or organs may be transported from a donor site to another location.
Tooth replantation saw further usage within the 17th and 18th century Europe, becoming popular nearing the end of the 18th century most often in the form of allotransplantation. In many cases, older wealthy patients whose teeth had decayed often paid poor people to have their teeth removed to be replanted in their own mouths. [ 12 ]
Liver transplantation is a potential treatment for acute or chronic conditions which cause irreversible and severe ("end-stage") liver dysfunction. [4] Since the procedure carries relatively high risks, is resource-intensive, and requires major life modifications after surgery, it is reserved for dire circumstances.
allogeneic, referring to allotransplantation or an allograft (from other individual of same species). xenogeneic , referring to xenotransplantation or a xenograft (from other species). References
