Stem Cells Derived from Human Clones

catbutt writes "Wired News reports that South Korean scientists have made a dramatic breakthrough by deriving stem cells from cloned embryos of patients with spinal cord injuries. It shouldn't be long before we can expect have a set of replacement parts ready when our own wear out." From the article: "Researchers must test the cells in animals before they can try the therapy in humans. But embryonic stem-cell researchers were shocked and delighted by the advance, which many had referred to as a distant possibility until they saw this study by Woo Suk Hwang and his colleagues at Seoul National University, which appears in the May 20 issue of Science."

    From TFA:

    Another striking aspect of the study, researchers said, is that Hwang was able to significantly increase the efficiency of his technique. Last year, when Hwang derived the first human stem-cell line from a cloned embryo, he failed more than 200 times before he succeeded -- meaning he had to use more than 200 eggs donated from women to create embryos. In his latest study, he brought the average number of tries down to just 20. That means in most cases one woman taking super-ovulating drugs in one menstrual cycle could donate enough eggs to create a stem-cell therapy for one patient.

    This is certainly good news, but human eggs are still needed, and from what I understand, harvesting them is still time-consuming, painful, and risky.

    From Aurora Health Care:

    Egg harvesting: Doctors commonly use an ultrasound-guided technique to harvest eggs. A laparoscopic method, which involves inserting a long, thin instrument with a light and lens through the abdomen, may be used if a diagnostic assessment of the pelvic organs is needed. However, ultrasound is faster, easier on the patient and as effective as laparoscopic retrieval.

    The doctor inserts the ultrasound probe with an attached needle into the vagina. Using the needle, the doctor punctures egg follicles and removes the fluid. The fluid is inspected and immediately placed in a sterile, nutritive culture material kept in an incubator.


    Ouch.

    A truly significant advance would be to use these stem cells to grow a human ovary in the lab, and harvest eggs from that. Such an advance would dramaatically decrease the need for additional female donors.

      There are millions of eggs in freezers already that will never be used. Instead of throwing them in the trash, maybe they could be used for one of the most important advances in human history. Just a thought.

      In the article, you'll see that one of the reasons why the technique was so successful is because they avoided using the frozen eggs. Freshly harvested eggs are better.

      So you are saying that I shouldn't get to choose where my taxes go regarding morally ambiguous activities?

      The federal funds that go into scientific research are always moderated by various groups that push and pull based on morals they feel are important, as well as those who push based on monetary objectives. Eventually, no doubt, stem cell research will be given more federal money.

      Further, limited or restricted use federal funds does not mean lack of funds, nor does it make this research illegal. It does restrict it somewhat since the way most research institutions are set up they can't seperate their different monetary uses enough such that if any one of them are doing stem cell research outside of the federal funding it puts other research there at jepardy for more federal funding.

      It is worthwhile to note that many, if not most, new areas of research do not get any federal funding until they've been proven using other funding or in other institutions/countries. The Gov't is very conservative at the beginning of new technologies, especially those which have such heavy ethical complications.

      The fact that the government is only providing very limited funding is very much in line with what they've done in the past, and I hope what they do in the future. I suspect too much money, for instance, was sunk into fusion at the beginning - everyone wanted to 'win' that race.

      Exactly. This could have been us...but now we get to play catch-up.

      It's often cheaper (and more rewarding the long run) to wait and play catch up. And believe me, if there is a real breakthrough you know that we'll catch up and likely surpass the leaders - and just as likely it won't be due to or held back by federal funds in any way.

      Neoconservative refers primarily to somebody's position on foreign policy.

They had very little to say about foreign policy, and a great deal to say about domestic policy, although when translated it mostly came out as "the market will take care of it."

      They were called "neoconservatives" to distinguish them from old-style conservatives, who were still in favour of various kinds of paternalistic government intervention, and very much tied to religious causes. Old-style conservatives were anti-civil-rights, pro-big-military, pro-God and anti-abortion. Neocons were pro-civil-rights, anti-big-military, non-religious and pro-choice.

      Other than a few policy advisory positions and Reagan's first budget chief, who didn't last long, the neo-conservatives never gained any significant degree of political power.

      GWB is not a neo-conservative. He's an old-style conservative. Neo-conservatism was a practical failure in the United States. The major neoconservative policy initiatives--like reducing government spending--were never even tried.

The latter are far too risk-averse to actually do anything *big*, so its pretty much left up to governments. By cutting off government funding for a particular avenue of research, you have effectively dictated that scientists in your country are not to persue that research.
