WASHINGTON: A medical facility reported on Wednesday that a genetically altered pig kidney is still functioning normally 32 days after being transplanted into a brain dead patient.
The experimental technique is a component of a developing body of research that aims to advance interspecies organ donation and, as a result, shorten transplant waiting lists.
In the United States, there are more than 103,000 persons on the transplant waiting list, 88,000 of whom require kidney transplants.
According to physician Robert Montgomery, head of the NYU Langone Transplant Institute, “this work demonstrates a pig kidney — with only one genetic modification and without experimental drugs or device sit is not rejected and can perform the same function as a human kidney for at least 32 days.
In September 2021, Montgomery performed the first genetically altered pig kidney transplant on a person. A similar treatment was again performed in November 2021.
Pig’s kidney given to brain-dead human in US
A pig’s kidney was successfully transplanted into a human on Wednesday, according to American surgeons, in a development that they believe may one day end the lack of organ donors.
The recipient was brain dead, meaning there was no chance of a recovery and they were already on artificial life support.
The kidney came from a pig that had undergone genetic modification to prevent the organ from being detected as “foreign” and rejected by the body.
Peer review and publication of the work have not yet taken place, but these things are planned. According to experts, it is the most cutting-edge experiment in the area thus far. Similar tests have previously been conducted on non-human primates, but not on humans.
The doctors attached the donor pig kidney to the recipient’s brain-dead blood vessels during the two-hour procedure at the New York University Langone Health medical facility to determine whether the recipient would accept the kidney or it would be rejected.
They meticulously watched the kidney during the course of the following two and a half days, doing several inspections and testing.
