Reprogrammed Skin Cells Turned Into Baby Mice
InfiniteZero writes "According to this WSJ story, 'Two teams of Chinese researchers working separately have reprogrammed mature skin cells of mice to an embryonic-like state and used the resulting cells to create live mouse offspring. The reprogramming may bring scientists one step closer to creating medically useful stem-cell lines for treating human disease without having to resort to controversial laboratory techniques. However, the advance poses fresh ethical challenges because the results could make it easier to create human clones and babies with specific genetic traits.'"
I am sure I am not the only one who is tired of hearing about ethical challenges that come with every small new incremental step in stem cell/cloning research. The issues haven't changed, they are the same as when cloning was first brought to the public spotlight when dolly was cloned; and they are the same as have been discussed in science fiction circles way before that.
Seriously, they freakin' took skin and turned it into another living creature! That is by far the coolest thing I've heard this week, and the only thing you can think of to say about it is something about ethical issues? That's like saying, "I invented artificial intelligence, but I don't know what to do about my ugly computer case, where can I get a nice one?" seriously, this is a problem that, while somewhat interesting, can be solved, is not particularly relevant, and really doesn't need to be discussed here.
Qxe4
I really don't understand how this experiment could be seen as controversial, as the cloning effort was to prove that an adult's cells could be reprogrammed to form any type of tissue, as opposed to harvesting our own young, which is clearly a practice with ethical question marks all over it. The focus was not cloning. We can do cloning well enough now. The technology already exists. What this research does mean is a glimpse into a future with no waiting lists for donor organs, no harvesting from the dead and far fewer rejection issues for new organs, as they would be your own tissue, from your own cells. Good stuff.

this is exactly what i'm talking about - i don't agree that a couple of cells constitutes a human being, so why should someone like yourself who this has zero impact on get to deny 100,000's of people potentially life saving treatments? i'd like to see these people against stem cell research look a kid dieing from organ failure in the eye, and tell him they don't believe cloned organs are worth looking into.
i think part of the problem is a lot of people have romanticised the idea of conception, if they were to actually go to a lab and see what they are protesting about they might alter their views.
If you mod me down, I will become more powerful than you can imagine....
I actually watched that video you linked. At what point does something similar to your link text occur? I must have missed it.
> Where do we draw the line?
I'm sure most of us agree we'll have to draw the line somewhere.
The first problem as you say is "Where?".
Whatever we choose will seem rather arbitrary, stupid and unsatisfactory to most people, but it's going to be even more stupid to not draw a line. Or worse- to draw many lines on a case to case basis.
Analogy: when you invent cakes, sooner or later someone has to draw the line and decide what can legally be considered a cake. It be seem silly, and the line may be redrawn later, but it will still have to be drawn. See: http://en.wikipedia.org/wiki/Jaffa_Cakes#Cake_or_biscuit.3F
Once we give ourselves a "power", it becomes our responsibility.
Which brings us to the next big problem. To me it seems like the scientists etc are merrily giving us "powers" way before we are ready.
To me, certain areas of research should be postponed till we are ready to draw the relevant lines.
Right now scientists and many other people keep saying stuff like "do it because we can", "don't stop progress", "don't be a luddite".
BUT this is NOT the same as being luddites or sticking our heads in the sand, this is in fact the opposite. This is seeing a potential issue in the horizon, and choosing to not charge at it, until we have a more well thought out plan of what to do when we get there.
The power to make "Jaffa Cakes" and biscuits is not a real biggie, but what should we do with human/animal/machine hybrids?
What makes you legally human? Killing a stray aka "free" dog and unplugging a brain dead human are considered different things legally.
At what points do we consider something human? Be very careful where and how the line is drawn, or many of us may end up not being legally considered human. If we draw the line another way, we might have to stop eating pigs, dogs, etc. The pigs might be happier (or not - since pig farmers will just close down their pig farms and leave them to fend for themselves aka die). It is no trivial matter. We already have enough problems convincing people what can and cannot be done with human embryos, imagine the problems with hybrid human-animal embryos.
If we are not prepared to draw certain lines yet, "don't go there yet" then. If we charge into things, the judges may not have enough understanding when they draw the first line, could then be a long and troubled wait till it is next redrawn.
There are plenty of other areas to do research in first (and limited resources anyway). Areas without such problems.
Lastly, even if a human embryo isn't much in the early months (or weeks), for symbolic reasons we could draw a more cautious (early) line. After all we for various reasons have chosen to elevate humans and human life above all other creatures. If we are going to value humans so highly, giving special value to a near brainless human embryo doesn't seem that stupid to me.
Plus if we don't, it might be harder to convince the future AIs or advanced hybrids to value humans and their embryos as highly ;).
