Behind The Knife: The Surgery Podcast

Xenotransplantation—the use of organs from other species to treat human disease—has long existed at the intersection of science fiction and surgical innovation. While early efforts were marked by limited success and ethical controversy, recent advances in genetic engineering, immunosuppression, and organ preservation have brought the field closer than ever to clinical reality.In this episode of Behind the Knife, we are joined by Dr. Joshua Mezrich to explore the history, science, and future of xenotransplantation. Through a narrative lens, we trace the evolution of transplantation from its earliest experimental days to the modern era of gene-edited porcine organs, highlighting key breakthroughs, ethical challenges, and the pioneers who shaped the field. We also examine the current state of clinical trials and what xenotransplantation may mean for the future of organ availability and transplant practice.Hosts - Madeline Cloonan, MD PhD, General Surgery Resident, University of Nebraska Medical Center, @maddie_
