Washington – Chinese researchers report new steps in the pursuit To plant organs from animals to humans With successful kidney transplant and hint on Wednesday until the pork liver may be useful in the end.
The Chinese patient is third A person in the world is known to live with a genetic modified pork kidney. The research team also told the same experience that cultivates the pork liver in a person in the brain.
Scholars Genetic change of pigs So their organs are more humane in the hope of alleviating the lack of transplants. Two initial carriers in the United States – Pork and Two kidneys pig It was short -term. But two additional pork beneficiaries so far Alabama woman Planted in November and New Hampshire a man Plant in January. The American clinical experience is about to start.
Nearly three weeks after kidney surgery, the Chinese patient “is fine”, and the pork kidneys work very well, said Dr. Lin Wang of Chicing Hospital at the Fourth Military Medical University in Xihan told reporters at a press conference this week.
Wang, a part of the hospital Xenotransplant, said the kidney recipient is still in the hospital for the test. Chinese media reported that she is a 69 -year -old woman who was diagnosed with kidney failure eight years ago.
But Wang pointed to a possible next step in swine transplantation – learning to plant the pinecide liver. His team informed on Wednesday in the journal Nature that the pork cultivated in a person extending in the brain had survived for 10 days, with no early signs of rejection. He said that the pork liver produced the yellow and albums – important for the primary function of the organs – although it is not as much as the human liver does.
The liver represents a complex challenge due to its various functions, including waste removal, the breakdown of nutrients and medications, anti -infection, iron storage and regulating blood clotting.
Wang said: “We find that he can work a little in a person.” He speculated that he would be sufficient to help support the failed human liver.
In the United States last year, surgeons at the University of Pennsylvania tried to support the “bridge” By linking pork liver pigs To the human body, which the brain dies to filter blood, such as dialysis of kidney failure. The American pig developer studies this approach.
In China, the Wang team did not remove the liver of the deceased person, instead cultivated the pork liver near it.
Dr. Parsia Favafi, a liver transplant surgeon at the Uti South Western Medical Center, who did not participate in the work, said. “We hope the first step but is still, like any good search, more questions than answers.”
Wang said that his team later replaced the human liver to another person who is to the brain with a pork liver and analyzes the result.
According to the media reports, another Chinese hospital last year planted a pig’s liver into a living patient after removing a piece of his cancerous liver, but it is not clear how that experiment appeared.
