Scientists Succeed in Growing Human-Monkey Embryos

Scientists have successfully grown human stem cells within macaque monkey embryos that were allowed to grow up to 20 days before being destroyed. The purported purpose of creating the chimeras is for experimentation and for organ transplant to humans, but this would require the embryos to be born, in which case, destroying a half-human would raise incredibly complex ethical issues. [These scientists apparently are incapable of self restraint and must be stopped by cultural forces, including laws, before they destroy everything. But who will lead this movement?

Scientists have created the world’s first monkey embryos containing human cells in an attempt to investigate how the two types of cell develop alongside each other. The embryos, which were derived from a macaque and then injected with human stem cells in the lab, were allowed to grow for 20 days before being destroyed.

We have a term for this type of life form: a chimera, named after the fire-breathing monster of Greek mythology that was part lion, part goat and part snake. It’s hoped that part-human chimeras—essentially  with some human organs or other characteristics—might one day offer clues to help us treat human diseases, as well as providing organs to transplant to humans. But for these purposes, part-human chimeras will first have to be born, and this research takes us one step closer to that eventuality.

That’s ethically controversial, because these creatures could possess an ambiguous moral status: somewhere between that of humans, which we don’t tend to experiment upon, and animals, which we do. How we end up treating part-human chimeras will depend upon the moral status we assign them—a task that these latest embryonic experiments only makes more pressing.

Why make chimeras?

There are several rationales for pursuing this line of research. Human-monkey chimeras could be created to study parts of the brain, for instance, so we can better understand Alzheimer’s disease. Another goal is to grow  for transplantation by “deleting” the relevant organ from the animal’s genetic instructions, and replacing it with  to fill the developmental niche.

Previously, the same researchers explored this avenue in pigs—seen as ideal because their organs are about the same size as ours. However, not enough  “took” to create a functional chimera, and the research failed.

Monkeys are evolutionarily closer to us, so there’s a greater chance that  will interact effectively with each other. The stated goal of the human-monkey experiments is to understand and perfect the development of chimeras in primates before transferring the technology to pigs.

As we intensively farm and eat pigs, there are thought to be fewer  with harvesting organs from pigs. Hence, primate research is a stepping stone, not a goal itself.

Future chimeras

Whether part-pig or part-primate, living chimeras that feature human cells are certainly possible in the future. How such animals would look and function would depend, in part, on the numbers of nonhuman and human cells. Previous experiments, for instance, have produced a goat-sheep entity that had both woolly and coarse hair.

This research clearly has the “yuck factor“, meaning it’s likely to provoke moral revulsion. If pigs or monkeys are eventually developed with humanized features, it could cause major public opprobrium, perhaps setting back public acceptance of science significantly.

Yuck factor is right!

These scientists are sick, demented and morally and spiritually dead! They have absolutely no regard for human life. In fact, they don’t know what life is – it’s all just a demented scientific game for them – an experiment to see how far they can totally distort and condemn life. I certainly wouldn’t want any organ from an animal!
