Monkey Cloning. Sort Of.

A whole slew of people have written about the announcement from scientists that they have "cloned" monkeys. Actually, in yet another case of bad science coverage (See my rant earlier today), they split an early-stage embryo. So, they really made artificial twins, which they then re-implanted into the mother. Still a heckuva a ways away from actually doing any sort of real cloning, IMHO.

      Ok everyone, I have read Huxley. My post was purely on the scientific potential of this development. Right or wrong was never part of the equation.

      Do I think this can be misused, certainly. So can anything. Do I think that it holds huge potential for scientific advance? Absolutely.

      Two major points to respond to:

      First Using identical twins for Nature v. Nurture is a good step, but identical octuplets would be even better. Especially ones separated at birth, and raised in different environments. I've never met such people. Now, I'm not suggesting trying this with people. Primates will do just fine. Maybe even white mice.

      Then we can make, oh, say, a hundred. And subject groups of ten to different environments. Lots of mazes for one group. Nicotine and alcohol for another. An overcrowded cage for a third. Gay rat parents for a fourth... See where I'm going? Can't do a controlled experiment like this with people. Animals, while still iffy, are much more palletable. (arguably I admit)

      Here is where we visit the Brave New World, but try to prevent it. If we can identify the environmental factors responsible for social stratification (other than $$ obviously ) then, if nothing else, we have a better informed public who is aware of the effects of addictions, education, lifestyle, abuse, etc. It will give people a better understanding, and thereby CHOICES.

      If as a result of gene-restricted testing, we can prove the effects of chemical exposure, learning habits, peer influence - well we can definitively solve a lot of prejudicial and assumption-driven problems. For example, there are still people who feel that blacks are inferior to whites. I'm not one, but you must admit it's true (that there are such people).

      Genetic baseline testing could rule out environmental factors. We could also subject different gene-bases to identical environments and quantify definitively the influence of gene differences. I know it's far off, but we CAN work in that direction, and at least address some of the fundamental questions.

      Second We can't effectively model in a computer those things that we do not really understand. Minds are one thing (that's handled in the above paragraph), effects of gene therapy is another thing. We can make reasonable assumptions, take educated guesses, and run sim after sim. But eventually, we'll HAVE to do live tests before such treatments can be applied to healing people.
      It would be tremendously helpful to keep individual genetic variations of the subjects down to a minimum, so any changes we see are likely not the result of individual differences. I.E. if all your tumor-prone subjects in the control group develop one as a result of a carcinogen, but your test group (with the same genome) does not develop a single one, then you can be reasonably sure (if your sample is large enough - like the aforementioned 100 monkeys (or 12 Monkeys :))) that your treatment is successful.

      If you can not rule out individual differences, you need a bigger sample (to reduce probabilities) and more tests for consistent results.

      So this 'new' technique for pseudo-cloning has great potential, without the added complexity of actual gene-level cloning. It has a slew of moral/ethical issues attached - but no fewer than cloning on the genetic level. It's less 'pure' than cloning, since even identical twins have genetic differences (always confused me WHY, but it's true) so true cloning is better for my suggested applications than these 'tweens'. I suppose that even pure clones will have genetic variation due to mutations during gestation, yadda yadda IANAgenetecist.

      And if the cost of tweening is much cheaper than that of cloning, which way will it go first? Right.

    The original article appeared in Science, you can find the abstract here.

    As it was mentioned by other /.ers here, this is real cloning, because cloning, in generally, means "getting something genetically identical". In especially, in molecular biology you often say about "cloning a gene", which has less in common with getting a dozen of Einsteins out of a bunch of Einsteins' hair.

    The goal of the study was twofold. First, it is the first time a nonhuman primate clone was obtained. Second, the idea is of making a large scale experiment to look for possible abnormalities and/or distortions of resulting clones, as well as differences among them.

    Another question was, at what stage of development is it safe to do the embryo splitting, e.g. is it possible to get a 32 cell embryo and divide it into 32 single cells, each resulting in a viable embryo?

    The authors did not answer all the question fully, they rather prepared the ground for research yet to come. There are a lot of things to test, the goal not being necessarly cloning of humans (or even monkeys) itself, but rather basic research on development of primates and establishing cultures of embryonic cells (which are, as you know, very useful, because they are able to develope into any mature cell of a given organism).

    Of course, getting genetically identical monkeys for drug research is also an issue, although I personally consider research on monkeys very questionable. Chimpansees are much more close to humans then most of the people think - if you haven't read any of Jane Goddals books on chimpansees, do not answer to this point of my reply. What I want to say is that I consider it to be more human to do the phase I drug research on human volunteers, yes, or even humans which are forced to do so - but are conscious of what is happening to them. Doing experiments on chimpansees is something like doing research on children for me.
