Obviously, actually having these organs in humans has created an incredible amount of forward inertia and excitement in the field and accelerated things, Montgomery said. This is what would happen if a regular pig organ were used for transplant; all humans have roughly one per cent of their antibodies devoted to attacking what are called alpha-gal sugars. Transplanting human parts (other than teeth and patches of skin) didnt really get going until the middle of the twentieth century. Pig heart valves have been used successfully for decades to replace damaged heart valves in humans, but until now the possibility of a fatal immune system reaction has prevented entire hearts from being transplanted.

"If this works, there will be an endless supply of these organs for patients who are suffering," Dr. Muhammad Mohiuddin, the scientific director of the university's animal-to-human transplant program, told the Associated Press. Dr. Bartley Griffith, the surgeon who performed the transplant, said the hospitals staff was devastated by the loss of Mr. Bennett. University of Maryland School of Medicine via AP, Doctors transplant a genetically modified pig heart into a human for the 1st time.

The pig-to-human surgery in Maryland was given emergency approval on New Year's Eve by the U.S. Food and Drug Administration through a provision that allows experimental treatments to be used when there is no other option to save a patient's life, the statement said. The NYU research in subjects considered deceased is different because it allows researchers to rigorously test, refine treatments and collect detailed data without fear that experimentation will take a patients life. So far the patient is doing well. The test was a step in the decades-long quest to one day use animal organs for life-saving transplants. hide caption.

His first mentor asked him to think about how many patients he could help as a cardiac surgeon, and then asked what he would think if he was told about a field that would help a hundred times more patients. So far . The method involves using gene-editing to "knock out" three genes from the donor pig's genome that activate a rapid immune system response in the human recipient, and adding six human genes that aid the organ's acceptance.

He had already been bedridden for six weeks leading up to the surgery, attached to a machine which was keeping him alive. And surgeons at the University of Alabama at Birmingham went a step further, transplanting a pair of gene-edited pig kidneys into a brain-dead man in a step-by-step rehearsal for an operation they hope to try in living patients possibly later this year. The victim, Edward Shumaker, spent two decades in a wheelchair, paralyzed from the waist down, and suffered numerous medical complications including a stroke that left him cognitively impaired before he died in 2007 at age 40, according to his sister, Leslie Shumaker Downey, of Frederick, Md.
