The successful transplantation of a pig kidney into a human recipient has sparked optimism among researchers regarding the feasibility of larger clinical trials involving animal organs. The recipient, Richard Slayman, is recovering well after the surgery, marking a significant step forward in xenotransplantation—the use of animal organs in humans. The kidney, obtained from a genetically modified miniature pig, demonstrated safety and functionality, showing promise for future trials. Discussions with regulatory authorities, including the FDA, are underway to plan further clinical studies involving pig organs, including kidneys, paediatric hearts, and livers for external connection.
