    Man Regrows Finger..could it work on us

    http://health.howstuffworks.com/extr...lar-matrix.htm

    hey just read this, thought it was pretty interesting. Last sentence mentions SCI. Does anyone know if and where they are doing it?

    Regeneration of a finger or limb is very different than regenerating the spinal cord. In the usual spinal cord injury, the cord is not severed. Many of the cells at the injury site die, as well as nerve fibers or axons that connect that brain and spinal cord. The spinal cord does not need to be regrown. The injury has disconnected many of the axons but the spinal cord almost never severed. If you have spasticity, the lower part of the spinal cord is still alive and kicking.

    Much evidence suggests that most axons in the spinal cord can regrow but the environment of the cord is not conducive for regeneration. This was first proposed by Aguayo and Sam David in the early 1980's, when they showed that axons from the spinal cord will grow in a peripheral nerve but not in the spinal cord. Martin Schwab then proposed that there is a protein in myelin that stops axonal growth and he showed this by using an antibody against such a protein (now called Nogo) in the 1990's.

    However, the story is now turning full circle. Several groups have now shown that axons in the spinal cord don't grow well unless they are stimulated to do so by increasing cAMP (a universal intracellular messenger). Once the cells are growing, they don't respond to growth inhibitors such as Nogo. Thus, it appears that spinal axons need not only certain conditions but also stimulation to grow.

    In 1991, more precisely. Almost twenty years ago.

    Lee Spievack- the guy who cut off his finger and re-grew IT.

    The chopped off finger guy was on Oprah a while back.



    Here is another link: http://www.dailymail.co.uk/sciencete...agic-dust.html (Warning it has a picture of the severed finger)

    I think 60 minutes also did an article on it a while back. I hope this astonishing medical recovery can improve our SCI lives.

    Dr. Young I am grabbing my pom-poms and keeping my fingers crossed that it can provide creative direction in your and other scientists/ doctors research pursuits towards a SCI CURE.
