Team of American and Chinese Scientists Announces Human-Monkey Hybrid Embryos Have Been Created
A team of U.S. and Chinese scientists have produced a series of human-monkey hybrid embryos in a study released Thursday that is raising critical bioethical questions about its experiments and their implications.
In the study funded by the National Natural Science Foundation of China and published in the journal Cell, scientists took six-day-old macaque monkey embryos and injected 25 human cells into each of them.
The type of human cells used are extended pluripotent stem cells, which can help develop both embryonic and extra-embryonic tissues, according to a Cell news release.
In a new study, researchers generate human-monkey chimeric embryos that are able to develop for up to 20 days.
