    Default Special thread for UGLY...Stem cell research news

    Based on some comments by UGLY in another thread I thought I would start a new post about stem cell research.

    IMO stem cell research seems to have many valuable areas of possible health "miracle cures" and will be our generation's "penicillin".

    Quotes from UGLY on stem cell research...

    Bone-repairing stem cell jab hope

    By Michelle Roberts
    BBC News health reporter in Oxford

    Doctors may soon be able to patch up damaged bones and joints anywhere in the body with a simple shot in the arm.

    A team at Keele University is testing injectible stem cells that they say they can control with a magnet.

    Once injected these immature cells can be guided to precisely where their help is needed and encouraged to grow new cartilage and bone, work on mice shows.

    The aim is to treat patients with injuries and arthritis the UK National Stem Cell Network conference heard.

    Professor Alicia El Haj, working with Professor John Dobson, also of Keele University, says the technology, patented by Magnecell, could be tested in humans within five years.

    It would provide a way to treat disease without invasive surgery or powerful drugs.

    The injection would use the patient's own stem cells, harvested from their bone marrow.

    These mesenchymal cells would be treated in the lab to give them a coating of minute magnetic particles.

    Use in scans

    These same magnetic nanoparticles are already approved in the US where they are routinely used as an agent to make MRI scans clearer to read.

    Targeted magnetic fields could then move the cells around the body to the desired place and switch them into action without the need for drugs or other biochemical triggers.

    Professor Al Haj said: "The ultimate aim is to repair cartilage and bone. We have been able to grow new bone in mice. Now we will look at whether we can repair damaged sites in goats.

    "We should be able to move to human trials within five years."

    Meanwhile, experts at the University of Southampton, led by Professor Richard Oreffo, have treated four patients with hip joint problems using stem cell therapy.

    The technique combines the patients own bone marrow stem cells with donor bone cells to patch-repair damaged bones that would otherwise need treatment with metal plates and pins.

    They say it is only a matter of years before their method could be used routinely to treat some of the 60,000 people who fracture a hip in the UK each year.

    If we don't fight hard enough for the things we stand for, at some point we have to recognize that we don't really stand for them.

    Cell swap may cure blindness

    By Roger Highfield, Science Editor
    Last Updated: 3:27PM BST 25 Sep 2006

    The most common cause of blindness in old age could one day be reversed with cell transplants into the eye, according to scientists.

    Researchers have improved vision in rats suffering from a disease similar to age-related macular degeneration using embryonic stem cells which can develop into any of the 200 types found in the body. The team that developed the treatment said that, if further tests show as much promise, they would try the approach on patients in as little as two years.

    The study is published in the journal Cloning and Stem Cells by Robert Lanza and Irina Klimanskaya at Advanced Cell Technology, Massachusetts, and Raymond Lund and colleagues at the University of Utah Health Science Centre.

    Retinal pigment epithelium (RPE) ? the cells that support the light sensing cells in the eye ? was grown from human embryonic stem cell lines and transplanted into the eyes of a special breed of rat that had an RPE defect, causing blindness. Afterwards, the spatial acuity, or the ability to see fine detail, was approximately 70 per cent that of normal rats.

    Stem cells could help cure deafness, according to new research

    BY ROSEMARY BLACK
    DAILY NEWS STAFF WRITER
    Friday, April 3rd 2009, 12:36 PM

    Add deafness to the list of conditions that someday may be cured thanks to stem cells. A new British study, published in Stem Cell Journal and reported on the Web site ChattahBox, says that fetal stem cells were manipulated by researchers to grow the auditory neurons that are necessary in order for someone to hear.

    University of Sheffield researchers don’t expect to be able to actually use the promising treatment on people for years, but one day, those who suffer permanent damage due to loud noise deafness could be cured.

    “This is really step one,” says Dr. Neil Theise, director of the liver and stem cell research laboratory at New York's Beth Israel Medical Center. “For years people have been saying that we could take these stem cells and turn them into the sensory cells that line the ears and detect sounds. Now they’ve done it. The stem cells have been able to be turned into this very highly specialized cell type. This is very promising.”

    In people who are deaf because of loud noise damage, these specialized auditory cells have been killed off, Theise says. But if they could be replaced with new cells made from manipulated stem cells, the hearing could be restored, Theise explains. Such treatment probably would not work on deafness that is present from birth, he says.

    So far, according to the ChattahBox article, researchers have only tried inserting the auditory cells into animals. It’s most likely five to ten years down the road before this would be tried in people, Theise says.

    Stem cell research is paving the way for cures in a variett of disorders, from diabetes to cancer to Parkinson’s disease. And British researchers have been successfully using stem cells as a treatment for macular degeneration, an eye disorder that plagues many elderly people, according to ChattahBox.

    Clinical trials for the deafness treatment may be starting on people within the next couple of years.

    That is all coulda shoulda woulda. Call me when they actually do something great besides MRI pictures. The point is that we cant justify wast here then condemn it in other areas. If this research never pans out the n this was a waste of money. Unless they find a cure for something it is a failure IMO, because that is what the scientists are selling to get the research money. This is supposed to be the breakthrough research anything less would be uncivilised.

    No line of investigation is a sure thing until after the fact. Research scientists use their expertise to determine which studies offer the best chance for success. They don't want to waste money on blind alleys any more than you do, and each one of them wants to be the one to make the big breakthrough. We have to trust their judgement and risk failure or let technology come to a standstill.

    I know Spider. I originally made the comparison of research spending for science and defence. Both that cost a lot of money and dont always pan out. Both are wasteful but it is funny that people are against wasteful defense spending.

    Wow, you sure don't recognize ground breaking research when you see it.

    In your quick read of the news stories you completely missed what the researchers have accomplished by your comment about better MRI's.

    Take some time, reread the news stories....

    What these articles are saying is the research is showing that these various cures are working in the animal trials... that is a very good sign these cures have a high probability of working for humans also.

    Oh, I didn't get that part. I guess it's because research is by nature uncertain so it's always a gamble, but the necessity of more and bigger weapons (defensive or otherwise) is debatable based on known facts.

    I still think your comparing apples and oranges with the science and defense argument. From what I saw the overages in defense spending weren't due to research not yielding useful results it was contractors who were given contracts to build things using existing technology not coming through on their promises.

    I'm sure people will argue that money going to defense R&D could be better spent elsewhere but if research for defense doesn't pan out, the money wasn't wasted.
