Surgeons at the University of Pennsylvania have achieved a groundbreaking milestone in the medical field by successfully attaching a genetically altered pig liver to a brain-dead patient. This remarkable feat marks a significant advancement in the potential use of pig organs to assist critically ill individuals with failing livers, offering hope and potential solutions for those in need of transplants.
Genetic Alteration and Experimental Procedure
The experimental procedure involved keeping the brain-dead patient on a ventilator while a genetically modified pig liver was connected to their circulatory system using a device called a perfusion machine. The patient’s own liver remained intact, and the pig liver sustained normal functionality for an impressive 72 hours. This successful demonstration showcases the potential for using pig organs to stabilize patients awaiting liver transplants or to provide temporary support for those whose livers may recover on their own.
Overcoming Rejection Challenges
The use of pig organs for human transplantation has long been an area of interest due to the scarcity of human organ donors. However, one of the significant challenges lies in the natural incompatibility of pig organs with the human body, as they are swiftly rejected by the immune system upon transplantation. To address this issue, researchers have turned to genetic modification, aiming to make pig organs more compatible with the human body. Through targeted genetic modifications, including the knockout of specific pig genes and the insertion of human genes, researchers aim to prevent immediate immune rejection and improve the overall compatibility of pig organs.
Future Prospects and Clinical Trials
The success of this experimental procedure paves the way for further refinements and advancements in utilizing genetically altered pig organs to support patients in need. The team at the University of Pennsylvania plans to conduct additional trials on brain-dead individuals, with the goal of refining the procedure for potential broader application. Additionally, eGenesis, the biotech company behind the genetic modification of the pig used in the study, is in discussions with the FDA to outline plans for early-phase clinical trials using their genetically modified pig system on patients with liver failure.
