Paralyzed Woman Walks Again 1196

mgv writes "It's been promised for years, but it's just become a reality. Stem cells taken from cord blood have enabled a paralysed woman in South Korea to walk again for the first time in 20 years. The details are on the Sydney Morning Herald Site which requires registration, but can also be seen on the World Peace Herald. Too late for Christopher Reeve, but not for the thousands of new injuries worldwide each year or the millions of paralysed people from other diseases in the world."

    Cord blood stem cells are considered to be adult stem cells, not embryonic stem cells. Just wanted to get that out before all the Bush bashing starts.

      However, embryonic stem cells are the cells which hold the real promise for research. This modern debate on embryonic stem cells is similar to the ban on using corpses for medical training and analysis in 16th century Europe. Sure you could learn some things by cutting open a dog. However, the real learning and advancement began once Human corpses were allowed for Medical research. History will view the ban on stem cells the same way. Think of all the good medicine we would not have today if some brave people did not push the issue of using corpses for medical research. Let the Bush Bashing resume.

        Embryonic stem cell research was not banned. Federal funding was given for embryonic stem cell research but limited to pre-existing lines.

        There is a huge difference between the two.

          Yet in practice there isn't. A lot of these lines have been ruined by mouse DNA and other issues. The best stem cell research, predictically, isnt from these lines but from others and most notably from foreign nations.

          Bush could have left the Clinton-era laws alone, but chose to give this as a handout to his religious right base. Its dirty politics any way you slice it. The moral issue is as manufactured as the PC you're using to browse this site.

        • However, embryonic stem cells are the cells which hold the real promise for research.

        Embryonic cells are growing too fast, and are too unstable. They end up growing into a mess, since they can't be told what to grow into.

        Adult cells are by definition those that are stable, having already grown into whatever their "children" will be. Embryonic cells (found in embryos with 1024 or fewer cells) can still grow into any type of cell, which we can't yet control.

        It's true that embryonic cells hold "promise", but it comes at a cost. While we're trying to figure out (through the research you want) how to keep a group of embryonic stem cells from growing into an amorphous blob of cells for a discordant mixture body parts, how much effort and money are we spending on it that could be better spent on adult cell research, or even more efficiently by developing a cholesterol-enhancing french fry?

        There's only so much money to go around. It's a balance between the far-off possibility of taming the embryonic cells versus the reality of using adult cells to fix broken bodies today.

      The government should be in the business for sure. The choice you give is a false-dichotomy. Is anyone really sugesting that those are the only two choices?

      The difference between Republican presidents and a hypothetical liberal president (we haven't had a liberal president in many many years) is that the Republicans would give companies research money ("corporate welfare") and then allow the companies to patent their discoveries for the purpose of making the most profit from every person who needs that medicine. At some level, there's going to be someone who is too poor to get cured.

      The hypothetical liberal president would also fund research, but publicly funded research would belong to the people who paid for it: the taxpayers. Everyone would have access to the new medicines, and even the poorest would be treated with them.

      Of course, you're thinking "that's not fair to the companies, and they'll go out of business". Note that I never said that. If companies want to make money, they can fund their own research with their own money, and sell their drugs themselves. Liberals aren't opposed to business and people getting rich. Liberals are just opposed to them getting rich at the expense of the taxpayers, or in an unfair/unethical manner.

      Okay, I'll bite on the last part, at least.

      Your question is misleading. The government should be in charge of funding basic scientific research that drives forward our understanding of physics, biology, chemistry, etc, and creates the platform on which industry can develop specific products.

      Why should the government do this? Because the results of fundamental research must be completely open and available to all scientists and entrepeneurs who would do something useful with it. Industry will *never* do that.

      Government-funded researchers invented the calculus, the mechanical (and electronic) computer, and the internal combustion engine, and gave that research to the public, so that commercial and charitable use could be made of them. Industry, on the other hand, is busy trying to patent your *genes*!

      "Stem cell research", as you can tell from the name, is not medicine, nor is it a commercial product. It is a fundamental piece of scientific research that advances our entire base of technology.

      So yes, the government should fund it.

      That's true, but make no mistake that Bush's policies have done more to hinder progress than accelerate it.

      For starters, it's a bureaucratic nightmare for labs--if so much as a single "bad" sample makes its way into an experiment, they can lose all government funding in a heartbeat. Labs end up having to spend a surprising and frustrating amount of time and money simply to meet the ever-growing list of compliance demands for federal funding. Angling for private funding is all well and good, but there's a severe lack of funding for pure science; corporate sponsors are far more interested in applied science. Applied science is important, but pure science is equally important and would suffer badly if it weren't for federal funding.

      Second, the stem cells in question are coming from discarded embryos from in-vitro fertilization clinics which are already slated for destruction. To ban these stem cells from research is hypocritical, at root--if the issue at hand is the destruction of a human life, they should be fighting just as hard to outlaw the practice of freezing embryos in the first place. That they're attacking the scientific link in this chain suggests that they're more against using these wasted embryos for scientific study (which, for various banal reasons, is seen as the arch-enemy of religion by many,) than they are upset about the wasting of embryos in the first place.

      It's a shame that the debate such that the scientific community is being made out to be the villian here. The real villian is the IVF industry; science is simply stepping in and trying to conduct incredibly promising research with something that'd otherwise be flushed down the drain without so much as a second thought.

    The article doesn't explain the important thing which is how they managed to inject enough stem cells into adult (for the adult to not reject them) from the small amount of blood available in an umbillical cord. There has only traditionally been enough (that the body's normal blood's anti-body won't attack) for a child's blood. Unless, they are talking about injecting it into the actually spine or something...I'm confused...

    The sound you just heard is that of a million scientists calibrating their bullshit meters. Seriously, if this is true it presents a moral and ethical alternative to those problems that have limited embryonic research, but bear in mind: Adult stem cells are not the same as ebryonic. They are more finicky (they are matched like organ donors), they create a limited number of cell types within the body and they are difficult to extract from an umbilical or placenta (which must be frozen immediately after birth). I would be more interested in stem cell warehouses for DNA types. Once you're born they save your umbilical stem cells like medical records (huge warehouses) free for one to use as needed throughout their life. The cash cow for the medical industry will be doing anything with embryonic stem cells, which are more easily ported across gene pools, and can replicate any cell within the human body. Don't make it a Bush/Kerry or USA thing. It's really not. That whole beef was about using government money to fund new embryonic strains.

    In lieu of any detailed description of this case in peer-reviewed scientific literature, this news item should be taken under advisement with appropriate skepticism.

    The spinal cord is an enormously complex structure, the exact neural connections of which are formed in early embryonic life. That you could simply inject multipotential cells into a damaged cord and expect them to differentiate and grow into mature neurons, complete with appropriate connections, is asking an awful lot. In addition, in this patient, "paralyzed" for two decades, you have the issue of muscles, bones, and joints that haven't been in use all that time.

      Agreed. IAAN (I am a neuroscientist) and at the Society for Neuroscience meeting a few weeks ago, there was a substantial amount of work being presented on spinal chord repair using stem cells. One researcher's results were scary: while the subject (rats if I recall correctly) were able to recover from SRI (Spinal Chord Injury) with the injection of stem cells, they developed allodynia, the condition where normal touch sensation of the skin is painful. This was because stem cells were not selective enough when making connections to existing fibers, and many of the new connections were incorrect. While this research does not mean the Korean team hasn't managed a substantial advance, it does mean that things aren't as simple as we might hope, and one should definitely view the Korean results carefully.

    While this is without a doubt something amazing and even blessed (I use the term loosely since I am atheist) it is only a glimpse into the potential for stem cells. Personally, I am very very moved by this event.

    But as one article [rednova.com] discusses, the whole point of using embryonic stem cells is that they are undifferentiated. The use of the cells used in the treatment of paralysis were supposedly cord stem cells and are more limited in which ways the body can put them to use. Embryonic stem cells, on the other hand, can in theory, be used to create ANY cell type in the human body. That is a tremendous difference.

    Ethical debates will persist from now until whenever but the moment people outgrow their need to believe in mythology, we'll make some better progress. I'm hopeful that there should be an ethically acceptable method for collecting embryonic stem cells so that we can make the real medical miracles happen.
