For the first time, scientists have created embryos that are a mix of human and monkey cells.
The embryos, described Thursday in the journal Cell, were created in part to try to find new ways to produce organs for people who need transplants, said the international team of scientists who collaborated in the work. But the research raises a variety of concerns.
"My first question is: Why?" said Kirstin Matthews, a fellow for science and technology at Rice University's Baker Institute. "I think the public is going to be concerned, and I am as well, that we're just kind of pushing forward with science without having a proper conversation about what we should or should not do."
Still, the scientists who conducted the research, and some other bioethicists defended the experiment.

(28,120 posts)The new study was performed in China and funded by Chinese government sources, a Spanish university, and a U.S. foundation.
Bioethicist Karen Maschke of the Hastings Center in New York says she is satisfied that the work, which passed layers of institutional review and drew on advice from two independent bioethicists, was performed responsibly.
Human-monkey chimeras do raise a worry, addressed in a report released last week by the National Academies of Sciences, Engineering, and Medicine (p. 218): that human nerve cells might enter animals brains and alter their mental capabilities. But that concern is moot for the chimeras in this study because they dont have a nervous system. They cant experience pain and arent conscious, says bioethicist Katrien Devolder of the University of Oxford. If the human-monkey chimeras were allowed to develop further, she says, that would be a very different story."

My understanding is that they intend to grow transplantable organs in these chimeras - am I understanding this correctly??
From the article....
The chimeras do not raise new ethical issues, bioethicists say, because they didn't develop long enough to acquire a nervous system.
IF the organs must mature in the
chimeras and are then havested, there's a big problem. Do organs and nervous system tissue not develop at the same time?
Can someone please help me understand this?

Dawn is set 10 years after the events of Rise, and follows a group of people in San Francisco who struggle to stay alive in the aftermath of a plague that wiped out most of humanity, while Caesar tries to maintain dominance over his community of intelligent apes.
Ten years after the global pandemic of a deadly Simian Flu,[a] the worldwide human population has been drastically reduced, with only about one in 500 genetically immune. Civilization is destroyed from the result of societal collapse. The apes, under the chimpanzee Caesar, all bestowed with genetically enhanced intelligence by the virus, have long-established a colony in the Muir Woods near San Francisco.....
