Whether and how new or old the technologies separately or together could be applied to replacing organs will thus remain a question of importance, today, tomorrow, and later in the future. So many different technologies have been developed, more useful than others. This research paper is going to discuss three different technologies that have been invented in response to the shortage of organs available for transplantation. ~Three points: Organ donation is de ned as giving an organ or part of an organ to be transplanted into another person. Organ transplantation is the only option to save lives in patients affected by terminal organ failures and improve their quality of life. One type of technology that has been developed is Allograft. Allograft is the transplant of an organ between two genetically non identical individuals. Due to the genetic difference, the donor’s organ will be treated as foreign by the recipient and will try to destroy it. This is called a “rejection transplant”. 2. The second type of technology is Isograft. The transplant of organ/tissue from a donor to genetically identical recipient is called isograft. There will not be any immune response hence no transplant rejection. 3. The third type of technology is Xenograft/xenotransplantation. Transplantation of organs/tissues forms one species to another species. For example, the heart valve of cow is transplanted successfully to humans. fi 1.
