This success is likely to pave the way for a new source of animal-derived organs. – The prospect of pig organs is expected to raise bioethical issues
Μία πρωτοφανής για τα ιστορικά χρονικά επιτυχία σημειώθηκε στη Νέα Υόρκη όπου για πρώτη φορά ένα νεφρό το οποίο αναπτύχθηκε στο σώμα ενός γενετικά τροποποιημένου χοίρου μεταμοσχεύθηκε σε άνθρωπο και λειτουργεί κανονικά.
Although many questions remain to be answered about the long-term effects of such an implant, experts believe that the achievement is a milestone in the field of xenograft (transplantation between different species of living beings). The operation was performed at the Langone Medical Center of New York University (ΝΥU), according to the New York Times, and the medical team that performed it, headed by him Robert Montgomery, Director of the NYU Langone Transplant Institute, has not yet been published in a medical journal.
The kidney came from pig which had been genetically modified so that the organ would not be rejected by the human body. The instrument does not transplanted normally, but was attached through blood vessels outside the abdomen, on the leg of a brain-dead man who was mechanically supported and who had previously been declared an organ donor. Το νεφρό άρχισε να παράγει ούρα και κρεατινίνη σχεδόν αμέσως. This success is likely to pave the way for a new source of animal-derived organs..
Montgomery stated that, as long as the organ functioned normally attached outside the body, it will probably work just as well if transplanted normally. «Things went better than expected. It looked like any implant I have used from a living donor. Many kidneys from the dead do not work immediately and take days or weeks to get started. This worked immediately».
The transplant surgery professor Dori Segev of Johns Hopkins University School of Medicine said: "We need to know more about the longevity of the instrument. But it is a huge step forward. It's a lot, very great achievement ".
Scientists have long been trying to develop organs in pigs suitable for transplantation into humans., as the waiting lists for various instruments are long (kidneys, heart, lungs, liver). Largely due to the lack of kidneys for transplantation, the vast majority of dialysis patients cannot acquire new organs.
The prospect of pig organs is expected to raise bioethical issues, in particular as to whether animals are being exploited by humans. So, while some doctors hope it is a matter of a few months before people start transplanting kidneys from pigs, others think it takes more time. Including, There are also concerns about swine viruses that could infect humans.
