Scientists perform the first pig-to-human lung transplant

In a groundbreaking medical first, scientists successfully transplanted a genetically modified pig lung into a brain-dead human patient, where it remained viable for nine days despite showing early inflammation. The procedure aims to address worldwide organ shortages—with 13 Americans dying daily while awaiting transplants—though researchers acknowledge several limitations must be overcome before xenotransplantation becomes clinically viable, including better genetic modifications and improved immune suppression techniques.
