Episode notes
Scale Of The Organ Shortage
- Over 100,000 people are on the U.S. organ transplant waitlist and about 13 die daily while waiting.
- Xenotransplantation (using pig organs) is a promising option to reduce this shortage.
Limits Of 3D Printed Organs
- 3D printing and organoids show progress but cannot yet recreate full organ vasculature and scale.
- Delivering nutrients and making micro-scale blood vessels remain major obstacles for printed organs.
Early Xenotransplantation Quackery
- Sergei Varanov in the 1920s implanted chimp and baboon testicle slices into men as an anti‑aging treatment.
- The practice likely produced placebo effects and posed serious infection risks.
