A study has confirmed that, Monkey embryos containing human cells have been made in a laboratory, US-Chinese team of researchers has sparked fresh debate into the ethics of such experiments.
As per to details, The scientists injected human stem cells which have the ability to develop into many different body tissues into macaque embryos, The developing embryos were studied for up to 20 days.
Such kind of experiments of so-called mixed-species embryos, or chimeras, have been produced in the past, with human cells implanted into sheep and pig embryos.
Prof Juan Carlos Izpisua Belmonte of the Salk Institute in the US, in 2017, helped make the first human-pig hybrid.
The scientist said that their work could pave the way in addressing the severe shortage in transplantable organs as well as help understand more about early human development, disease progression and ageing, added that “These chimeric approaches could be really very useful for advancing biomedical research not just at the very earliest stage of life, but also the latest stage of life.”
He further added that the study, published in the journal Cell, had met the current ethical and legal guidelines, “Ultimately, we conduct these studies to understand and improve human health,” he said.
