-- "David Bennett, 57, who had his heart swapped out for the heart of a genetically modified pig at University of Maryland Medical Center is doing well days after undergoing the historic transplant surgery. He had been ruled ineligible for a traditional heart transplant at UMMC." --
SCIENCE YO! -- "To genetically modify the heart, three genes were 'knocked out,' according to the health system, that are responsible for causing an “antibody-mediated” rejection of pig organs in humans. Another one also was 'knocked out' to prevent excessive growth of the pig heart tissue. Six human genes were inserted that encourage immune acceptance of the pig heart." --
