Bid to counter organ transplant shortage
LAHORE: In what could be dubbed a dramatic and history-making bid to solve the organ transplant shortage, scientists have **w created pig-human embryos through a gene-editing technique.
The latest edition of a re**wned British newspaper “The Guardian” has reported: “Scientists trying to grow human organs inside pigs in an attempt to tackle a shortage of do**rs have successfully created part-human, part-pig embryos. Researchers at the University of California, Davis combined human stem cells and pig DNA and allowed the embryos to mature for 28 days, before terminating the experiment and analysing the tissue. Researchers will soon have the means to study embryos beyond the 14-day legal limit. Does the potential for advances in medicine outweigh ethical concerns? They believe the animals, which if they had been carried to term would have developed a human internal organ, but would have looked and behaved like any other pig. The goal is that in the future, similar animals could potentially act as a ready source of organs for life-saving transplants.”
The newspaper has gone on to write: “It was reported earlier this year that scientists had begun attempts to create the embryos, but there has been opposition from authorities. In September last year, the US National Institute of Health said it would **t back research into “chimeras” until it knew more about the implications. It cited fears that the presence of human cells could affect the animal’s brain and behaviour, potentially making it more human. Prof Pablo Ross, the reproductive biologist leading the research, sought to calm those fears, saying there was a “very low potential for a human brain to grow.”
