Xenotransplantation: When Organs Aren’t Human

What happens when science pushes the boundaries between species? In this episode of The Cadaver’s Lessons, we explore the fascinating — and controversial — world of xenotransplantation: the transplantation of animal organs into humans.
From ancient myths about hybrid creatures to modern genetically engineered pigs created with CRISPR technology, xenotransplantation has evolved from science fiction into a real medical frontier. We break down the history of organ transplantation, the immune system challenges that have plagued researchers for decades, and the groundbreaking pig-to-human transplants happening today under FDA compassionate use approvals.
But with innovation comes ethical debate. Should animals be genetically modified and bred for human survival? Could xenotransplantation increase the risk of zoonotic diseases? And if this technology becomes widely available, who gets access — and at what cost?
Join us as we unpack the science, ethics, history, and future implications of one of medicine’s most controversial advancements.
