The kidney was examined on the affected person for 2 days throughout which it labored correctly, filtering waste and producing urine.

Scientists temporarily attached kidney from one of these pigs to a human body and watched it begin to work, a small step in the decades-long quest to one day use animal organs for life-saving transplants.
