Pig kidney shows the way.
Finally we are seeing cross species organ transplantations. Till now heart transplantation with pig's heart seemed to have failed. Two persons who received pig's heart were unable to succeed the transplantation. On one patient the immune system rejected the transplanted heart. Recent report about a man named Richard Slayman ( 62 years old) whose kidney was transplanted, however , is showing good result. He is producing urine, balancing the body's fluid, removing waste product from the blood etc. His doctor at Massachusetts General Hospital seems quite hopeful to see the results.
