According to The Telegraph, American scientists have made significant progress in the field of transplantation by successfully transplanting a genetically modified pig kidney into a human. The kidney was specially altered by undergoing 69 genetic modifications to reduce its differences from the human kidney and make it safer for the patient. The operation, which lasted four hours, was performed on March 16 in the United States and was successful.

The patient, Richard Slayman, who previously underwent a human kidney transplant, is now recovering rapidly under the close supervision of medical professionals. Although his long-term prognosis remains unknown, the operation was the first of its kind, opening up new prospects for patients with kidney failure. In previous human brain-dead experiments, pig kidneys have functioned for 77 hours, 7 days, and 32 days.

Michael Curtis, CEO of eGenesis, the company that raised the genetically modified pig for the operation, expressed his gratitude to the patient for his contribution to the development of science and medicine.

"This is a new frontier in medicine that demonstrates the potential of genetic engineering to change the lives of millions of patients around the world suffering from kidney failure," he said.

Earlier in September last year, surgeons in the United States had already transplanted a pig's heart into a human, who became the second patient in the world to undergo such an operation. Two days after the procedure, the patient began to joke and could sit in a chair.
