Most mammals have these sugars, but humans dont. This was not an easy road, he said. If the method of genetically modifying donor animals so that their organs are less likely to be rejected by human hosts proves successful in the long-term, such procedures might be an option for many other patients awaiting transplants. Hospital officials said they could not comment further on the cause of death, because his physicians had yet to conduct a thorough examination.
