Xenotransplantation It is known that the need for organ transplants outweighs the available donors. There have been several research advancements that claim they will help with the demand for organs, one of these is xenotransplantations. Xenotransplantation is a transplant that comes from a different species; this can be tissue or organs. In this paper we will explore the medical implications and requirements for the xenotransplants. We will also discuss the ethical implications by presenting arguments for and arguments against this type of transplant. In doing this, we hope to better understand of all issues involved in xenotransplants. Medical Background of Xenotransplants In old literature and in myth, we note that the concept of xenotransplantation is not new. Take for instance the Centaurs (half man, half horse) and Satyrs (half man, half goat) from Greek mythology, which shows that it was at the very least thought of. The first report of a successful xenotransplantation was in the 17th century, a surgeon was reported to have completed a bone xenograft from a dog’s calvarium to a human skull. (Siemionow & Eisenmann-Klein, 2010). Other types of xenotransplantations occurred between the 17th and 19th centuries in which most of them ended in failure. Why they failed was not know until more recently in the 1940’s, when (Baskette & Ritz, 2010) “Research… gave scientists a better understanding of the role the immune system played in organ donation” (p. 6). When juvenile diabetes was first identified, the only way to treat it was with xeno insulin made of extracted insulin from the pancreases of cattle and pigs. The cost to purify the insulin and the high risk of allergic reaction lead researchers to look for other options. In the 1980’s insulin synthesis made a huge leap. Biotechnology was able to manufacture human insulin in a lab. Now, most insulin
