    Glial scars

    Is there any proven method to remove a glial scar permanently? I understand Chondroitinase is a potential option, but from what I've read administration of the enzyme is difficult, and results aren't permanent, correct me if I'm wrong. Does UnTethering surgery do anything to a glial scar, it is used to help with large growing cyst (synrix) on the spinal cord correct? I think getting Past these scars is essential for effective regeneration to take place whether by stem cells or therapy. Maybe even for a epidural stimulator to be more effective.

    It is not necessary to remove "glial scars." Many rat studies (Kai Liu, Paul Lu, Mary Bunge) have shown that axons grow across the injury site. It is foolish to suggest that the injury site should be "cut out."

    Why do you write stuff like this Jim? This forum is supposed to be educating and you know how many researchers that disagree. At least write that some suggest that glial scars is not the problem. I know Wise works from this hypothesis but most researcher seem to see the scar as a big issue. And just because something is possibly doesn't mean it's inhibitory.
    Debating on CareCure is like participating in the special-olympics. You may win, but you're still disabled.

    I would never suggest that, I only asked if untethering surgery had any effect on a glial scar. But that's good to know it's not absolutely necessary just curious if there could be potential for more recovery if it was out of the picture.

    I understand that the word "remove" was not the best term to use,, should've used dissolved, disintegrate see where you thought I was talking about cutting it out now, my apologies.

    Studies are underway right now to find out more about these very suggestions. We should start hearing something this winter on preliminary results.

    Any idea what labs?

    Yes. I can get back to you within the next week or two with more information on what I'm allowed to discuss (if anything). If a paper is being written, there will be nothing to discuss until after it is published.

    Yes Void, this forum is absolutely about education.

    I wrote the above because James asked a question and I offered my opinion. There is concrete evidence from independent labs that many, many axons grow across the "glial scar." He is newly injured and has been led to believe the injury site needs to be removed because it prevents regeneration. How did he come to believe this? Are there research studies that show the injury site prevents regeneration? It is scarey to me that he thinks a piece of his cord needs to be cut out for him to recover.

    He never mentioned any cutting.
    In the introduction Silver discuss the topic: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3334458/
    If it's your opinion say it and why, and don't act like it's a indisputable fact. To say that the other opinion is foolish when so many researchers support it is not a very desirable scientific discussion.

    Void, the following is a recent review article that I wrote about spinal cord regeneration. It is very detailed and cites many researchers in the field.

    By the way, there is an error in the article that I did not catch during proof-reading. In the abstract, where I say "Blockade of Nogo, CSPG, and their receptors indeed can stop axon growth in vitro..." and I really meant "Blockade of Nogo, CSPG, and their receptor indeed can stimulate axonal growth in vitro...".
