The history of advances in transplantation is, arguably, more accurately understood not as a history of surgery but as a history of immunobiology. The pig had 10 genetic alterations: one was designed to prevent the recipient's body from rejecting the pig heart, another aimed to keep the pig's heart from growing post-transplant. That label will come if Bennett has a good quality of life for months, he said.
