It was only with the advent of effective immunosuppressants that transplants began to work consistently. That label will come if Bennett has a good quality of life for months, he said. The transplant heart was surgically removed from the donor pig before the surgery on the human patient; pig organs are considered suitable for transplant to humans because they are about the same size and shape.

Although it's been tried before one of the earliest subjects, known as Baby Fae, survived 21 days with a baboon's heart in 1984, according to Time the practice has fallen into disuse because the animal organs are usually quickly rejected by their human host. Allogenic refers to being foreign, but from the same species. Its all about going into the first living human trials with as much data as we can possibly have and make it as safe as possible and effective, said Dr. Robert Montgomery, the director of the NYU Langone Transplant Institute. A kidney, unlike a heart, can be taken from a living donor, and kidney transplants developed earlier. The researchers also prevent the expression of genes that would allow the heart to grow larger once inside the person receiving the transplant and exposed to human growth hormone. In the early hours of January 7th, the cardiothoracic surgeon Bartley Griffith, unable to sleep, went to his kitchen to make coffee. 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. To do a trial in a living human, you need to know that its reasonable to believe the trial will give the patient over all a better outcome than not being in the trial, Montgomery said.
