Xenotransplantation, or the transplantation of living tissues or organs from one species to another, alleviates the shortage of human organs such as heart and kidney. For example, the xenograft will be readily accepted by athymic nude mice, severely compromised immunodeficient (SCID) mice, or other immunocompromised mice (Morton and Houghton, 2007). This book considers the scientific and medical feasibility of xenotransplantation and explores the ethical and public policy issues surrounding the possibility of renewed clinical trials. What are the ethical aspects of using animal organs to save human lives? Results.There was significant up-regulation of all intragraft cytokines tested (interleukin [IL]-2, IL-4 . Allograft, also called allogeneic transplant, homograft, in medical procedures, the transfer of tissue between genetically nonidentical members of the same species, although of a compatible blood type.Allografts are commonly used in the transplants of skin, corneas, hearts, livers, kidneys, and bone and bone marrow, although transplants of the last often come from relatives. Diabetics in advanced stages may receive a xenograft as a means of restoring a section of skin on the feet or legs that has deteriorated as a result of the disease. This is likely to occur when there is no human organ readily available and the patient’s condition is critical. An allograft is a transplant between two members of the same species who are not genetically identical. Also, a system of proteins in the body called "complement" are activated whenever pig organs are transplanted into primates, leading to severe systemic toxicity. This book assesses the potential impact of the Final Rule on organ transplantation. The tissue standards do not apply to products that do not meet the above description, including those that have tissue-like names or are otherwise associated with tissue usage.

The term xenograft refers to a tissue or organ that is derived from a species that is different from the recipient of the specimen. graft from one individual to another of different species. The immune response to a xenograft is generally more extreme than that seen in same species transplantation, and it ultimately results in xenograft rejection, or in severe cases, recipient death. However, primates are not ideal as donors anyway for other reasons including the small litter size, the long latency before pregnancy is possible, and the high frequency of viral infection among primates.
