The pigs' kidneys were frozen for a year, what happened next could save millions of lives

Researchers at the University of Minnesota have made significant advancements in organ preservation, extending the viability of pig kidneys for months. They successfully thawed and transplanted these kidneys back into pigs, demonstrating restored color and urine production, indicating normal blood flow and function. This breakthrough involves cooling organs to -150 degrees Celsius using a chemical cryoprotectant to prevent ice formation. The team collaborated with the mechanical engineering department to develop a solution with iron oxide nanoparticles to minimize damage during thawing. The goal is to apply this technique to human organs in the future.
