Transplant in Boston: Patient with pig kidney can leave hospital. With the help of pigs, doctors are trying to counteract the shortage of organ donors.

In the USA, they recently transplanted a kidney that had been grown in the animals for the first time. Now the patient can go home. It is said that it filters toxins from the blood, keeps body fluids in balance and produces urine. Two years ago, a pig organ, a heart, was transplanted into a human for thefirst time.
