Vicissidude writes "According to WorldNetDaily scientists in Korea report using umbilical cord blood stem cells to restore feeling and mobility to a spinal-cord injury patient. The research, published in the peer-reviewed journal Cytotherapy, centered on a woman who had been a paraplegic 19 years due to an accident. After an infusion of umbilical cord blood stem cells, stunning results were recorded: 'The patient could move her hips and feel her hip skin on day 15 after transplantation. On day 25 after transplantation her feet responded to stimulation.'"

Benefit of the doubt (Score:4, Insightful)
However, giving them the benefit of the doubt, it is too bad the field of stem cell research in the US has been badly damaged by policies the current Whitehouse administration have put into place. A good number of scientific teams formerly here in the US have had to leave the country to continue their work and others are having to modify their protocols to use one of the "acceptable" lines of stem cells the Bush administration in their infinite wisdom have seen fit to approve for scientists that want to continue to receive federal funding for their work.
It should be noted that it is not just patients who have been paralyzed that can potentially benefit from this work. Other potential therapies to come out of stem cell work include treatments for heart disease, retinal vision loss disorders, Parkinson's disease, Cystic Fibrosis and many others.

It's too bad that the OP doesn't understand that umbilical cord blood stem cells are not embryonic stem cells, but rather adult stem cells. But you and he are obviously blinded by politics because you fail to see that the US government is funding this kind of research very heavily.
(BTW, there are ethics involved in research of all kinds, in engineering, in law, in business, etc. You simply do not agree with the idea that ethics should be a part of stem cell research.)

I hope you don't get modded down here, because it's a good point. I might respect the position of someone who, after much deliberation, believes that embryonic stem cells should be used. However, anyone who thinks that using embryonic stem cells is a no-brainer either doesn't understand the ethical considerations at stake, or simply doesn't believe in ethical considerations at all. Ethics is tricky business, and neither "the ends justify the means" nor "all's well that ends well" are sufficient ethical justifications.
And yes, also the research here was done with umbilical cells, and the US government has absolutely no problem funding research using umbilical cells. The federal government simply put restrictions on the funding of gathering fetal cells, which is a long way from outlawing stem-cell research.

OK, I'll play, but only because I'm curious. What is the ethical problem with using embryonic stem cells from fertalized eggs that are being thrown away from a fertility clinic? They are other wise going to be thrown away or disposed of, so why not put them to use?
What I get confused with is how people are against that particular use, yet aren't against the fertility clinic itself, which outside the scope of this argument is throwing away fertalized eggs...aka "murder" to the extremists.
Now granted, there are plenty of other ways to use embryonic stem cells as well, but weve completely killed on good use but claiming all uses are bad.

THAT's the issue. Once it becomes legal to create human beings to kill them the society has legalized ghouls.
That statement also shows the inextricably parallel issue of defining when human life begins. By definition, the choice to end a human life, especially one which has viable potential, is...shall we say...controversial.
Under legal definitions which were decided by U.S. courts, not the U.S. society, human life starts after the baby's head exits the mother. That's an over-simplification, true.
Rhetorical point: When does a baby truly become a person? When does a minor truly become an adult?
Can you see it from the perspective I just described?

On a related note, given the huge number of people who want to adopt babies and can't find them as well as the people with fertility challenges, it seems to me a better way to "settle" the "issue" is to avoid it by making those fertilized embryos available to other people.
"No, that embryo will be destroyed (and you can't have it to have a baby of your own.)" is heartbreaking to a lot of people.
I've not been there myself and really don't know what would be involved. This is just an idea that came to me after watching friends struggle to have children.

Embryos being disposed of and prisoners who are given life terms being killed early are two very, very different things.
The main argument trumpeted by people against embryonic stem cell research is that embryos are worthy of "being saved," which is to say, they have "moral value." These same people, to be consistent, have to be against forms of very early abortion and even some forms (if not all forms) of contraception.
The basic thing that vexes these people is that they have never studied the potentiality principal. They think the mere fact that an embryo has the potential to become a human being gives it moral value, makes it "worthy of being saved." This is because they know human beings have moral value, and so conflate "a thing with potential to be something of moral value" with "a thing that has moral value." However, this argument is spurious, as I'll try to show.
For one thing, many things have the potential (i.e., have some causal relationship) to the creation of a healthy infant child. As someone else once suggested to me, one such thing is a glance of flirtation toward a fertile young woman. From that glance, there exists the potential for intercourse; from that intercourse, the potential of conception; from that conception, the potential of a human child in the form of an embryo.
If that example seems too cooked up, think about miscarriages. Hundreds of thousands of "babies" die from miscarriages every year. So, since that constitutes an essential mass death of a significant portion of the human "population," shouldn't we be devoting massive scientific research dollars to stopping miscarriages?
The reason both these things seem absurd is because saying that embryos have moral value is completely arbitrary. Harm cannot be done to embryos in the same way harm cannot be done to chairs or rocks. The chair or rock doesn't have a hope, an aspiration, or a direction which is thwarted by the said harm. The rock or chair doesn't care about the said harm. The crux of the matter is, the rock or chair isn't conscious, and that's why they have no moral value.
The only people who might care about the rock or chair's harm is the owner of the said rock or chair. But that is only due to a relational property between the owner and his objects, and hasn't a thing to do with morality. (For example, when considering whether humans have the right to harm other humans, it serves no one to say, "Okay, but what if the person harmed were your mother?" Introducing the familial relationship simply distorts the inherent morality of a thing, since it makes the decision relational, based on other notions such as loyalty to one's family, etc.)
The reason we see harms to dogs or cows as worse than harms to chairs is because we know that dogs or cows can a) experience pain, b) in dying or being severely harmed, be deprived of their right to continue the life they were already living. Chairs experience no pain, conceive of no harm, and have no life of which to be deprived.
One can make an argument for defending the late-term fetus (which may be conscious) from abortion, but preventing the embryo from use in scientific research based on the idea that the embryo is a "human life" is, morally speaking, quite unsound. This is because embryos have no moral value of their own. They are things which may, one day, become things of moral value, but that does not mean they are morally valuable now.
To take to your prisoner example, human beings have moral value even if they are savage criminals sentenced to life imprisonment. This is because they are conscious human beings who still have a right to life within our moral framework. Using them from scientific research sets a moral example that humans, in general, are usable in har

Erm, this is a perfect example of why it is people like you that keep us from moving ahead. You had a knee jerk reaction and did not actually read what I wrote. Specifically, I wrote "for scientists that want to continue to receive federal funding for their work. So, what you fail to understand is how much research is funded by the federal government. If you are unable to acquire NIH funding, that severely limits the type and extent of research that can be accomplished given the current academic infrastructure.
Stem cell research can be funded by state or by private organizations. Also, there is nothing limiting research other types of stem cells.
True, but those funds are very very small compared to the types of funding that the federal government delivers. Also, Universities prefer to receive federal funding because of the indirect costs. In fact, in some situations, it is difficult to maintain a position at a University in biomedical research without federal funding.
If you hate that the Bush Administration puts America in a bad light, why do you aid the cause by spreading misinformation which makes America look far worse than it really is?

Abstract:
HLA-matched UC blood-derived multipotent stem cells were directly transplanted into the injured spinal cord site of a 37-year-old female patient suffering from spinal cord injury (SPI). In this case, human cord blood (UCB)-derived multipotent stem cells improved sensory perception and movement in the SPI patient's hips and thighs within 41 days of cell transplantation. CT and MRI results also showed regeneration of the spinal cord at the injured site and some of the cauda equina below it. Therefore, it is suggested that UCB multipotent stem cell transplantation could be a good treatment method for SPI patients.

Here come the Stem Cell tirades (Score:5, Interesting)
Stem cell research is a boon to medical science. Umbilical stem cells, which in no way hurts anyone (and which only a few outsider whacko groups are against), have proved invaluable to health care research. Embryonic stem cells (the ethical problem) are even more invaluable.
Here is the problem. As an individual, I support the legality of abortion. I don't like the fact that it's necessary at times, and I'd be glad to see it discouraged in any positive way possible. I can respect those who come to the painful realiziation that they simply cannot support a child due to serious personal issues (be it drug abuse, abject poverty, mental illness, etc). And conversely I have absolutely zero respect for those who terminate simply because it wouldn't suit their lifestyle. One is little different from an animal reabsorbing their fetus under stress, and the other is not far from infanticide out of convenience. And while I do not consider an embryo or even a fetus to be a "baby", I don't consider them mere biological byproducts of sex either.
In a limited, controlled, publicly accountable fashion, I can easily accept open stem cell research. Let's not beat around the bush - whatever the origin, you're destroying a human embryo for medical and research gain. When that embryo is the castoff from fertility work (ie spare embryos that had a chance but will never be complete), it's not so bad. But there's just something questionable about creating a human life simply to dismantle it.
I don't consider abortion infanticide unless it's late term (ie the fetus could actually survive with a little medical assistance). It's not an independant being yet, and it's by no means an infant until it can at least breathe without a machine (not counting injury/deformity). But in at least a limited way, once a fertilized ovum undergoes it's first cell division (not at fertilization, as it hasn't become a new entity yet), it has become a new human in every sense that a fetus or a toddler is. To say it's anything less is no different from saying that a baby or a retarded person is less human than you are. I'm not even talking about souls or religion - I have grave doubts about both subjects. To me, it's just the most logical conclusion.
So... while I applaud the wonders we can perform with placental and umbilical stem cells, and would like to see that research continue at full speed, I can more than understand why some people don't like seeing their tax dollars go to embryonic stem cell research. I personally don't care for the idea of creating human organisms, concious or not, simply for the gain of others.

I have known about this for some time, but because I didn't want to be guilty of the same hyping that is so often engaged in by some therapeutic cloning proponents, I waited until it was published in a peer reviewed journal. Now it has been and the news is HUGE: Korean scientists have used umbilical cord blood stem cells to restore feeling and mobility to a spinal cord injury patient. I have no link, but I do have the report published in Cytotherapy, (2005) Vol 7. No. 4, 368-373.
The patient is a woman who has been paraplegic from an accident for more than 19 years. (Complete paraplegia of the 10th thoracic vertebra.) She had surgery and also an infusion of umbilical cord blood stem cells. Note the stunning benefits: "The patient could move her hips and feel her hip skin on day 15 after transplantation. On day 25 after transplantation her feet responded to stimulation. On post operative day (POD) 7, motor activity was noticed and improved gradually in her lumbar paravertebral and hip muscles. She could maintain an upright position by herself on POD 13. From POD 15 she began to elevate both lower legs about 1 cm, and hip flexor muscle activity gradually improved until POD 41." It goes on from there in very technical language.
The bottom line is this, from the Abtract: Not only did the patient regain feeling, but "41 days after [stem cell] transplantation" testing "also showed regeneration of the spinal cord at the injured cite" and below it. "Therefore, it is suggested that UCB multipotent stem cell transplantation could be a good treatment method for SPI patients." (My emphasis.)
We have to be cautious. One patient does not a treatment make. Also, the authors note that the lamenectomy the patient received might have offered some benefit.

It is one of those issues that has been clouded with talk of abortion (usually by opponents ESC research), and thus reasonable discussion is frequently overwhelmed by hysterical chatter that doesn't even relate to the topic.
If you are cool with IVF, then there is little reason to be upset about ESC research. If you aren't cool with ESC research, then it seems illogical to be ok with IVF. Abortion really does not enter into the discussion.

As the kid gets older, and eventually middle-aged, the nerves grow and catch up with development. In later years, the nerves will have grown so long that singnals will take longer time to reach their destination, causing longer reaction times. On the other hand, there is the benefit from increased wisdom, coming from the ability to hold longer thoughts in the nerves.
As the peron is reaching the endpoint of his life, at around 80 years of age on average, the nerves will have grown immensely, making him a treasure trove of deep thought and information. This can be hard to ascertain though, as the sheer nerve-length means they now have to grow in circles in the limited space of the human body. This means that you will often hear the wisdom of the past, as thoughts that started in one end, reach the other. The cramped conditions also predispose for spontaneous reconnections between nerves, causing apparently random changes of subject.
