    Australian Research Team Finds Stem Cell Gold in the Nose
    from www.lifesite.net
    March 22, 2005

    BRISBANE, March 22, 2005 (LifeSiteNews.com) - Dr. Alan Mackay-Sim and his small team of researchers at Griffith University have just published the results of a four-year study of stem cells obtained from the inside of the nose. Their work shows once again that adult stem cells can be made to change into any cells in the body without the medical or ethical problems of embryo cells. Mackay-Sim said almost any kind of tissue in the body could be obtained from olfactory stem cells including heart cells, brain cells and nerve cells, without immune system rejection or formation of tumors.

    The cells are being hailed not only for their flexibility but for the ease with which they can be harvested - a ten-minute procedure that is not dangerous and only mildly uncomfortable. They also seem to have the advantage, unlike bone marrow stem cells, of very readily reproducing in the lab. The team was able to culture millions of them and grow a wide variety of tissue samples very easily.

    While the big Australian universities such as Monash are well-funded in their destructive embryo research, Mackay-Sim's team made this progress on a few hundred-thousand a year. In fact, one member of his team found himself so strapped that he had to leave the work to manage a grocery store for a time.

    "It has been a disregarded area of research generally," Mackay-Sim said. "Whenever I presented a paper, the feedback I would get was that our work was 'interesting but weird'."

    The findings have so excited the Australian scientific community that Tony Abbott, the federal Health Minister, indicated it may influence the vote when legislation allowing research on in vitro embryos comes up for review.

    Abbot said, "If adult stem cell research is as prospective as this particular project seems to suggest, well, then all those moral dilemmas we were wrestling with a few years ago and will have to wrestle with again when the legislation [permitting the use for research of excess embryos created through IVF before April 2002] comes up for review, we may be delivered from."

    George Cardinal Pell, the Catholic archbishop of Sydney said, "I hope it will [lead to that]. I think it deserves to be evaluated with the full rigour and I hope that after that rigorous assessment we'll see just how significant this is. I think there is a real possibility that [the Griffith University scientists] have made an enormous contribution."

    Great now we can use them without damaging anything, hopefully no religious crack pot will be up in arms about the sanctity of the nose.

    Just proves there is always a better way of doing things if you look for it.

    And look they did. Scientists aren't amoral, if there is a noncontroversial way of getting somthing then they will go to that.

    We "religious crackpots" have never had an issue with adult stem cells, or even umbilical cord stem cells. We have an issue with embryonic stem cells because it cheapens the life of those human embryos from which they are harvested.

    question .... in order to have my daughter we had to resort to science

    i had over two dozen embryos in a freezer at a doctors office.....what should i have done with them.....

    I was not calling people who had issue with embrionic stem cells crack pots. Iwas saying that a person who took that issue and painted olefactory stem cells with the same brush would in my oppinion be a crack pot.

    Hair Provides New Stem Cell Source
    By Jennifer Viegas, Discovery News
    March 29, 2005

    Any being with hair or fur might be able to supply his or her own stem cells for medical treatments, according to a new study that found stem cells in hair follicles can develop into nerve, skin, muscle and pigment cells.

    Medical applications have not yet been fully determined, but researchers suspect that a minimally invasive follicle pluck could allow burn victims to regenerate skin, hair loss sufferers to regrow natural locks, and people with neurological disorders to reconstruct damaged nerve tissues.

    The new stem cell source, while not a replacement for the myriad of cells that scientists have generated from embryos, also presents an avenue of stem cell research that likely will prove to be less controversial than other stem cell studies.

    Hair follicles, the bag-like structures that rest just below the skin and are responsible for hair growth, have been probed as a source for stem cells since 1990, but the new developments have put follicles into the stem cell limelight.

    "We were able to recently make the hypothesis that hair-follicle stem cells could form neurons and other non-follicle cell types when we observed that hair-follicle stem cells expressed the protein nestin, which is also expressed in neural stem cells," said Robert Hoffman, professor of surgery at the University of California at San Diego and president of AntiCancer, Inc.

    "This gave us the idea and impetus to make our discovery that the hair-follicle stem cells could actually differentiate to neurons (nerve cells)."
