They have kept pig lungs functioning with human blood, paving the way for animal-human transplants - called xenotransplantation - in as little as five years. ❋ Unknown (2010)
The main ethical problems included the health risks for the transplant recipient (e.g., a substantial risk of hyperacute rejection and graft-versus-host disease), traditional animal ethics issues, concerns about informed consent (complicated by empirical uncertainties and the possibility of legally mandated life-long health surveillance), fair allocation of health care resources, and the public health issue that xenotransplantation would allow viruses to jump the species barrier into humans. ❋ Streiffer, Robert (2009)
The possibility of a public health crisis arising from a transmissible infection crossing species boundaries, a significant concern with xenotransplantation, is greatly reduced when the source of the biological material is human and the recipient a non-human animal confined to a laboratory. ❋ Streiffer, Robert (2009)
The hope, he believes, lies in xenotransplantation, essentially a process of growing organs from animals that are compatible with a recipient's immune system. ❋ Unknown (2009)
The early discussion of ethical issues raised by chimeras occurred under the heading of xenotransplantation, the use of non-human animals as a source of cells, tissues, or organs for transplantation into humans (Institute of Medicine 1996). ❋ Streiffer, Robert (2009)
On a remote island in Lake Superior, scientists struggle to solve the problem of xenotransplantation -- using animal tissue to replace failing human organs. ❋ Scifirantergirl (2007)
We are displacing animal habitats, importing nonnative species when we move or migrate, feeding meat products to herbivores, dining on exotic predators, and experimenting with animal hybridization, xenotransplantation and precursors to bio-terrorism in a world made smaller by staggering advances in transportation and global commerce. ❋ Unknown (2007)
Many scientists have called for a moratorium on xenotransplantation until such dangers have been overcome. ❋ Unknown (2005)
“That remains the principal anxiety associated with xenotransplantation,” said Warrens. ❋ Unknown (2005)

Still there was enough concern around the issue to prompt the US FDA to create guidelines and a xenotransplantation committee to oversee the area. ❋ Unknown (2004)
Wasn't that xenotransplantation, and she made it more than minutes, right? ❋ Unknown (2004)
Sugars aren't the only problem in xenotransplantation, though. ❋ Unknown (2004)

This includes organ and tissue donation and preservation; tissue injury, repair, inflammation, and aging; immune recognition, regulation, effector mechanisms, and opportunities for induction of tolerance; histocompatibility; drugs and pharmacology relevant to transplantation; graft survival and prevention of graft dysfunction and failure; clinical trials and population analyses; transplant complications; xenotransplantation; and ethical and societal issues. ❋ Unknown (2010)
