Researchers Create First Genetically Modified Monkeys 134

Posted by Soulskill from the didn't-we-just-see-this-movie dept.
Several readers tipped news that U.S. scientists have created 'chimeric' monkeys, made with genetic material from as many as six different genomes (abstract). This is significant because it's the first time researchers have used the technique on a primate. From the article: "Researchers took very early stem cells, called totipotent stem cells, from separate developing embryos and basically glued them together, implanting the mixed embryos into surrogate mother monkeys. The cells — from totally different sources — didn’t fuse, but worked together in harmony, forming fully fledged, normal, healthy animals. ... The key here was the scientists’ use of totipotent cells, so named for their ability to differentiate into the totality of possible cells in an animal. A totipotent cell can give rise to a whole animal. Pluripotent stem cells, the type most frequently used in stem cell research, can differentiate into any cell in the body, but can’t become a whole animal, and can’t make other embryonic tissues like a placenta. Totipotent stem cells are only derived from the very earliest stages of a zygote, mere days after fertilization. In humans, totipotent cells differentiate into pluripotent cells after four days."

    I assume since the immune system is trained up together, there aren't issues with tissue rejection? Since scientists have created a way to turn ordinary skin cells into pluripotent stem cells (via a viral gene therapy process), are there any plans to try to reach this totipotent stage as well?

      Chimeras occur in nature and AFAIK there are no negative health effects so I don't think tissue rejection is an issue...

      • But, cross-species chimeras? I'm not familiar with that in nature.

            I suppose if the stem cells were fused it would be cross species but it's pretty clear they are seperate stem cells developing independant of eachother in the same womb.

        It is an probably an issue, but I'm not a biologist, geneticist, or anything related to medicine. What I do know is that females are far more likely to be chimera than males, and autoimmune disorders are far more prevalent in females than males. It seems likely that there's something going on there.

    Let's set aside all religious and moral/ethical concerns and look at the practicalities. A chimp with near-human intelligence would be a tremendous asset to both the military and private economy. They are much stronger and faster than humans, so would be incredible soldiers. They can ALREADY use sign language to communicate with humans, so just imagine taking that a step further--being able to type or write messages, maybe able to mimic human spoken language.

    They would make great athletic coaches, especially for gymnastic training and the like. They would be good nannies and playmates for kids, and could defend the kids from nasty people even more effectively than could a dog.

    I guess that leads to the idea of chimeric dogs. Just imagine a dog smart enough to identify someone and testify against him in court. "Yes sir, that's the perpetrator. I can smell him a mile away."

If they get it into their head to attack, for many times unclear reasons, they instinctely follow a pattern of destruction of the enemy primates body. first they will gnaw off your child's fingers. Then they attack your precious little one's face by biting off parts. They then start to dismember, ripping off limbs.

      Mixed-gender chimeras happen in real life. In general it's not a huge problem for the organism. One part of the animal contains the sex organs, and those organs are appropriate for the genes in that part. The hormones are often wacky, of course. Yes, you can get hermaphrodites this way.

      You may be under the impression that a chimera is a homogenous mix of cells from different gene lines. Actually, the gene lines usually occur in 'clumps' throughout the organism. The right arm might be all one gene line, while the torso is another, and the left arm yet a third. The clump around the lower abdomen will determine which sex organs develop.

      • It shouldn't be that important. The only gene that determines gender is TFT, and all that does is make the testes form... everything else gender-specific is a consequence of the hormone produced there. So long as the gonads are of matching gender, the organisism as a whole should present as one gender anatomically. It's only if the chimeric line happens to run between the gonads that you'd get weird hermaphroditic outcomes.
        • Typo, sorry: Meant to say TDF.

        • Well, TDF may be the only gene that determines gender, it's certainly not the only thing that determines how a fetus develops. The hormonal environment in the womb also has a huge effect, and seems to have a significant impact on sexual orientation as well as physiology. IANA biologist, but I suspect that the number of "natural" hermaphrodites resulting from chimeric mergers is vanishingly small.
