The researchers conducted an extracorporeal circulation experiment using a genetically modified pig liver on a dead human model. This method has been shown to be feasible and has provided effective temporary liver support with minimal need for immunosuppression. During the experiment, the integrity of the xenograft was maintained, meaning that the pig liver remained functional without severe rejection reactions. Metabolic and hemodynamic stability of the patient was maintained even after removal of the native human liver. The research was published in the journal Nature Medicine and represents a potential advance in the field of transplants and replacement of damaged livers. This approach could provide a solution for patients waiting for a liver transplant in the future.
