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.
An allograft contains many of the beneficial characteristics of nerve autograft, such as three-dimensional microstructural scaffolding and protein components inherent to nerve tissue. [3] One of the adverse effects of nerve allotransplantation is the immunogenic response.
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.
Allograft offers the best regeneration quality but has lower volume stability. Often a mix of different kinds of bone grafts is used. [citation needed] In general, bone graft is either used en bloc (such as from the chin or the ascending ramus area of the lower jaw) or particulated, in order to be able to adapt it better to a defect.
Xenotransplantation is a cross-species tissue transplantation from animal to human. [10] [11] The development of blood vessel anastomosis opened the door for xenotransplantation during the 20th century, which led to numerous attempts in organ transplantations with tissues from nonhuman primates (NHPs).
CHICAGO (CBS) -- Two sisters have grateful hearts after they both received heart transplants at the same age—seven years apart. Younger sister Meredith Everhart and older sister Abbey Cannon are ...
Transplant engineering (or allograft engineering) is a variant of genetic organ engineering which comprises allograft, autograft and xenograft engineering. In allograft engineering the graft is substantially modified by altering its genetic composition. The genetic modification can be permanent or transient.
The suspect in the New Orleans attack that killed 10 people on New Year's Day did not act alone, US investigators believe. Shamsud-Din Jabbar, a 42-year-old US citizen, is believed to have driven ...
