Human-Monkey Chimera Embryos Spark New Debate on Ethics
Proponents say chimera experiments could lead to a new source of transplant organs. An image from a timelapse of the monkey-human chimera Cell Monkey embryos containing human cells have been developed in a laboratory, a study by a global team of researchers confirms. The development sparks new debate on the ethics of experiments on "chimera" embryos, whose cells come from two different species. In the new study, the researchers, led by Prof Juan Carlos Izpisua Belmonte from the Salk Institute in the US, detail their experiments with cells from a long-tailed macaque and a human. They reveal t...
