This is a presentation on xenotransplantation, which is the transfer of organs or tissue between two different species. This area of scientific research is making significant headway in the world of transplantation and may save thousands of lives in the near future. An explanation of what xenotransplantation is and what it must overcome in order to be successful is the starting point of this discussion. Following this introduction, is a discussion of the latest research in xenotransplantation and the knowledge gained through each study. The concerns of the risks involved are also addressed with varying views of where xenotransplantation is headed. In the hopes of reducing risks and allowing the research for cross-species transplantation to continue, the presentation ends with the regulations set forth by the Public Health Service.
