Ethical issues of transplanting organs from transgenic animals into human beings

One of the most important applications of transgenic animals for medical purposes is to transplant their organs into human's body, an issue which has caused a lot of ethical and scientific discussions. we can divide the ethical arguments to two comprehensive groups; the first group which is known as deontological critiques (related to the action itself regardless of any results pointing the human or animal) and the second group, called the consequentialist critiques (which are directly pointing the consequences of the action). The latter arguments also can be divided to two subgroups. In the first one which named anthropocentrism, just humankind has inherent value in the moral society, and it studies the problem just from a human-based point of view while in second named, biocentrism all the living organism have this value and it deals specially with the problem from the animal-based viewpoint. In this descriptive-analytic study, ethical issues were retrieved from books, papers, international guidelines, thesis, declarations and instructions, and even some weekly journals using keywords related to transgenic animals, organ, and transplantation. According to the precautionary principle with the strong legal and ethical background, due to lack of accepted scientific certainties about the safety of the procedure, in this phase, transplanting animal's organs into human beings have the potential harm and danger for both human and animals, and application of this procedure is unethical until the safety to human will be proven.
