Soto both before.Historically, these surgeries have mostly failed, because the human immune system attacks the foreign tissue, even with immunosuppressive drugs.
But if that animal organ is genetically modified to trick the human immune system into accepting it, scientists could theoretically prevent rejection.According to Toby Coates, a clinician scientist at the University of Adelaide who was not involved in the current case, the new xenotransplant was made successful using a 'key advance' in genetic modification.
The removal of four pig genes and the insertion of six human genes, he says, helped"prevent coagulation and 'humanize' the pig kidney". These human-like pig kidneys were functional for a week in the patient's body, but researchers now need to test whether these kidneys areEither scenario would be extremely welcome. Today, in the US, roughly 40 percent of patients waiting for a kidney transplant die within five of years of being listed.with end-stage kidney disease.
Unfortunately, one successful xenotransplant isn't enough to declare this solution safe or effective.
