In this photo provided by the University of Alabama at Birmingham, surgeons prepare to transplant kidneys from a genetically modified pig into the body of a deceased recipient in September 2021. The experimental procedure was a step-by-step rehearsal for operations they hope to try in living patients possibly later in 2022, part of a quest to use animal organs to save human lives.
