To our surprise however, we found that the iPC cells lost the ability to initiate tumours as subcutaneous xenotransplant
Besides selecting the adequate species (possibly hog) and solving pending technical problems, unlike genetic modification or molecular fabrication in plants or other organisms, genetically modified animals used in xenotransplants
, and in research in general, confront us with a problem that has not been debated much in bioethics.
However, there are limits to the utilitarian argument for xenotransplants
seem more directed at xenotransplants
than chimeras, although the line
The new method has the potential to avoid the immune-rejection problem and make xenotransplants
After an introductory chapter outlining major philosophical and religious approaches to environmental ethics, Christine Gudorf and James Huchingson present twelve case studies: the Everglades, persistent organic pollutants, endangered ecosystems, nature preserves, nuclear waste disposal, ecosystem restoration, degraded coral reefs, hydropower, desertification, genetically modified foods, hunting, and xenotransplants
The cases deal with genetically modified foods, sport hunting, and xenotransplants
of animal organs.
Gene therapy, recombinant DNA research, designer babies, organ transplants, xenotransplants
, artificial organs, life-extending medical treatments, and bold human experimentation seemed to threaten traditional concepts of human boundaries.
He ends his survey with a look into the future and concludes that that future is bright because of scientific advances in xenotransplants
, genetic research and improvements in immuno-suppressants: 'Novel scientific advances .
Early step to making transgenic pigs for xenotransplants
, or transplants of organs from species other than homo sapiens, also may occur at a greater rate in the future, provided that formidable immune system barriers between species can be overcome.
In Part II of this paper, we set out the potential health benefits for recipients of xenotransplants
, along with the associated risks to recipients and the wider population, addressing both scientific and ethical concerns.
Presented only in Italian at a Vatican news conference, the 11,000-word document was the fruit of a Vatican working group made up of 23 church ethicists and international experts in animal organ transplants, known as xenotransplants
The FDA regulates all clinical use of xenotransplants
in the U.
Referring to his exhibits as "anatomical artworks," von Hagens updates Fragonard for the age of xenotransplants
and genetic chimera.
