The Unfolding Science of Xenotransplantation: Trends and Issues.

It is truly fascinating how the modern Medical Technologies are quickly updated and made more effective by the Doctors and Scientists nowadays. One of the potential studies in this field is the use of Xenotransplantation, commercially known as the cross species transplant of organs and other body components. Xenotransplantation is still on its developing process with so many potential and risks. Many criticisms are also being thrown at this issue, but there are still so many matters that should be taken into deep consideration before creating judgments, especially when it’s a gambling of being able to save and prolong one’s life. Advances in the area of science and medicine opened up opportunities for improvement of health. Many diseases which ought to be incurable or too critical were now found ways to be treated in a safer and more efficient manner. One of the known medical processes which have been going through a lot of improvement and innovation for more than a century now is Transplanting of organs. Transplanting are known to have three main types—the Isograft which involves transplant of organ or tissue between identical twins only, the Allograft which involves transplant between two species of the same kind, and lastly is the Xenograft which involves transplanting between two different kinds of species (Lewis 600).

Guevara 2 The main focus in this research paper will be the Xenograft, a process also known as Xenotransplantation. The most popular and controversial kind of Xenotransplantation is the animal-to-human transplant in which according to Dickinson, may take place in different forms such as solid transplantation of animals, cell therapies, use of animal cells in gene therapy, and use of noble animal cells as a part of medical device (Dickinson, “Potential uses of Xenotransplantism,”). This is because many scientists have found great potential in using animal parts as a replacement for human organs which have already failed functioning. Berschorner stated that it may also coordinate with other medical processes such as stem cell and tissue engineering technology (Beschorner, “The Future of Xenotransplantation”, http://e.medicine.medscape.com). Xenotransplantaion, as modern as it sounds, is actually not that new to science. It was said that Xenotransplantation’s first attempts were recorded in 1905(Fano, “What’s wrong with Xenptransplantation?- A campaign for responsible Transplantation”). Since then, many procedures and experiment on enhancing this process followed. In 1906, the first ever vascular transplanting of kidneys from a pig and dog to a patient was done by Jaboulay (Beschorner). In the early 60’s, other people such as researchers from Tulane Medical Center conducted a set of experiment by transplanting chimpanzee kidneys to humans with renal failure with very minimal success. One of the recipients was able to live for 9 months which motivated researchers to focus more in this process and thus, pushed the era of Xenotranplantaion in America (Salomon, and...
