A US man has become the first person in the world to get a heart transplant from a genetically-modified pig. David Bennett, 57, is doing well three days after the experimental seven-hour procedure in Baltimore. The possibility of using animal organs for so-called xenotransplantation to meet the demand has long been considered, and using pig heart valves is already common.
Pigs are increasingly becoming popular candidates for organ transplantation. This is because their organs are anatomically similar to those of humans. What’s more, porcine components are more tuned for genetic engineering.
