The development of the Uniform Donor Card in the U.S., a legal document that was recognized in all states, made organ donation more straightforward, and the 1984 National Organ Transplant Act established some legal ethics for the field, prohibiting the sale of organs and providing a framework for trying to distribute organs fairly. In January, surgeons at the University of Alabama at Birmingham reported that they had for the first time successfully transplanted kidneys from a genetically modified pig into the abdomen of a 57-year-old brain-dead man.

The kidneys were monitored for more than fifty hours, after which the experiment ended. A total of 106,657 people are on the national transplant waiting list, and 17 people die each day waiting for an organ, according to organdonor.gov.
