Xenotransplantation - implanting organs from one species to another - is a growing field and scientific advances could help address organ transplant shortages. 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. It was driven by companies that would drop a bunch of money without knowing the science. He released the clamp, allowing human blood to flow into the organ. Have our feelings about the extraordinary weirdness of transplants changed much over the centuries? It read, Good luck with the surgery! But Griffith and his colleague MuhammadM.
