Human "Cloning" Makes Embryonic Stem Cells 111

Med-trump writes "Scientists at the New York Stem Cell Foundation Laboratory have reprogrammed an adult human egg cell to an embryonic state using cloning technology and created a self-reproducing line of embryonic stem cells from the developing embryo. Lead researcher Dr Dieter Egli said: 'The cells we have made are not yet for therapeutic use. There is clearly more work to be done, this is early days. We see this as a step on that road, so now we do know that a human egg can turn an adult specialised cell, such as a skin cell, into a stem cell.'"

            Would that include the Nazi experiments on the Jews in concentration camps? I know that is an extreme example, but I raise it to underscore that there are some things which we should not do, even for science. (Which to me is the highest of all goals.)

      Not sure where you gents get your news, but the juvenile bias certainly shows ("anti-choice"? Really? Grow up already).

      Nobody with any sense complains about adult stem cells. Each adult has billions, if not trillions of those to spare. Nobody has to die in order to procure them.

      Now how about you tell us how successful embryonic cells are versus adult stem cells? I'll save the arguments - the adult cells tend to work far better for the intended purpose. Turning those same cells into 'embryonic' ones may lead somewhere, they may not. OTOH, it still means the source wasn't a separate and distinct human being that had to be destroyed in order to produce them (which is the whole kick against the embryonic ones in the first place), so I don't foresee any major (or credible) theological or moral opposition to the idea.

      Now, where are those downmods from scores of angry people, most of whom cannot comprehend an opposition based on one honest moral concept?

        I'd call them what they want to be called, "pro-life," if only there was any evidence that this were an accurate description of their stance - say, because it tended to coincide with other "pro-life" beliefs, such as opposition to war and capital punishment, or advocacy for healthcare for people who can't pay for it. Overwhelmingly, this hasn't been the case. If you are the exception to the rule, then wear your 'pro-life' badge with pride, I guess. But the vast majority of the kooks with giant fetuses on picket signs don't warrant such a generous phrase. And, mysteriously, the distinction between different kinds of stem cells is overwhelmingly lost on them - the very people to whom the difference should matter most.

        I'm sure you know very well that the definition of "human being" is what the whole argument is about, so using that term as if it were just a universally agreed-upon fact, does you no favours.

        • because it tended to coincide with other "pro-life" beliefs, such as opposition to war and capital punishment, or advocacy for healthcare for people who can't pay for it.

          Actually, if you look at basic Christian religious beliefs, you'll find that consistency in most of them. In any Catholic church, asking around will find all of that to be true.

          So your point was what - a strawman argument?

          • You got the wrong thing from the post. There was sarcasm. The stereotypical (USA) pro-lifer follows the Republican belief system. No abortion, but plenty of money for the military, and a strong death penalty. Like the rest of the Republican belief system, strongly contradictory stances presented together without blinking.

          • if you look at basic Christian religious beliefs, you'll find that consistency in most of them.

            you need to define the terms "basic" and "christian", and the inclusion of the qualifier "most" renders the strawman accusation toothless. It seems like a setup for the no true scotsman fallacy [wikipedia.org].

          • by sjames ( 1099 )

            I agree that the religion itself deserves the term pro-life and it may well be that most of it's members do as well, but the vocal and political "religious right" does not. They apparently need to spend more time listening to their clergy and reading the Bible.

      • That argument doesn't get any more lucid by repeating it.
        The excess embryos used to harvest stem cells will die anyway. If they're not used to harvest cells they'll go in the bio trash bin.
        And if a bunch of a couple dozen to hundred cells is worth calling a human being is highly debatable. Remember you shed way more living cells when you take a dump or blow your nose, and each and every one is viable as we know since Dolly the sheep.

        ("anti-choice"? Really? Grow up already).

        Yes really. Pro-life is the more emotionally charged term because it casts the other side as anti-life, which is inaccurate. One side cares more for the life and well-being of the fetus, while the other cares more for the life, well-being, and freedom of the parent (you could argue for the freedom of the fetus too, but you aren't really taking control away from something that has no control over the situation in the first place).

          All this "telling women what to do with their bodies" mantra is extremely one-sided and a stellar example of a strawman argument.

        But you see, the whole point is that every single cell in your body that has a full complement of your DNA is, potentially, a separate and distinct human being. A zygote is, potentially, a separate and distinct human being.

        The conjection is wrong because moral objection to destroying a human being or potential human being is not the only foreseeble moral theological opposition to this idea. Since there is quite general views among my Muslim brothers on this subject

        Except, that's exactly not doing science. Your argument is that, you understand how one thing works a little, and you don't see proof yet that something else may be better, ergo you assume it's not worth pursuing. What if, embryonic stem cell research (and only embryonic) required the sacrifice of 1 million IVF embryos (all of which were in the process of being discarded), but the resulting research would cure 100 million people a year of disease? What if it's 1 billion people a year, or 1000 people a year?

      • If you think that ESC are completely redundant with adult stem cells, why do you think researchers are still pushing for ESC research? Even if you presume to be an expert in the field, it's awfully arrogant to assume you know better than the rest of the field.

      Actually, they left the egg DNA in and added a full set from the donor cell as well, so the resulting stem cells have excess genetic material. They are not viable in the sense that they could develop into a human being.

      The point of that was simply to determine if the removal of DNA from the egg was the point where human cloning was failing. This research says yes, the step of removing the existing DNA from the egg is the step that caused human clones to fail.

    • Normal human cells have two complete sets of DNA on how to build a human being.

      Eggs have 1 complete set - (sperm has another - when you combine them you get two sets)

      End result has 3 sets of DNA on how to build a human being.

      Two of the sets come from an adult.
