Scientists have been trying to produce pigs whose organs would not be rejected by the human body, a research effort that has picked up steam over the past decade because of new gene editing and cloning technologies. The other ethics issue is around the consent, he said. Doctors have transplanted the heart from a genetically modified pig into the chest of a man from Maryland in a last-ditch effort to save his life.

Doctors were working without any substantial knowledge of the human immune system and its role in accepting or rejecting transplants; it was as if one were trying to treat diabetes without knowing about insulin. The transplant surgeons saw that rejected organs were infiltrated by cells; trying to understand the mechanism prompted the tremendous bloom in immunobiology. What happens to your body when you're an organ donor? Drugs for suppressing the human immune system, Including an experimental medicine, were also used in the patient. In the past month, researchers at NYU Langone Health transplanted pig hearts into two people who had recently suffered catastrophic heart failure and were left brain dead but remained on life. The surgery took place on Friday (Jan. 7), and after four days the human patient is breathing on his own, although he is still connected to a heart-lung machine to strengthen his blood circulation, according to a statement from the University of Maryland Medical Center (UMMC).

He had been deemed ineligible for a human transplant, a decision that is often taken by doctors when the patient is in very poor health.

Its C.E.O., Martine Rothblatt, has a daughter with pulmonary arterial hypertension, and the company has funded research on lung xenotransplantation. Bennett's son praised the hospital for offering the last-ditch experiment, saying the family hoped it would help further efforts to end the organ shortage. On 7 January 2022 a team of US doctors successfully transplanted a gene-edited pig heart into a patient with terminal heart disease. CNN Sans & 2016 Cable News Network. 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.
