Spinal cord regeneration?
Doesn't say that explicitly, but I suppose there's a chance. I suspect we'll hear more about this.
Note that brain tissue doesn't regrow (at least in these mice). So nerve regeneration may be as yet out of reach.
Spinal cord regeneration?
From this Heber-Katz link:
Spinal cord Regeneration: The Heber-Katz laboratory has been examining the regenerative response of the spinal cord as well. Most recently, they found scar tissue is a key blocking element in axonal regrowth. Thus, spinal cord transection where fibroblastic infiltrates are kept to a minimum results in recovery of function or coordinated walking within 3 weeks. They are testing various molecules that can block scar formation to determine its effect on healing and function. One such molecule, apolipoprotein E, along with its receptors, appears to be upregulated during a regenerative response.
Bingo. This could be as big a development as the discovery of penicillin. Of course, if it leads to the average human lifetime being extended to biblical dimensions all sorts of social complications will ensue.
I live for the day! Come on now!
They did say the optic nerve came back. So maybe?
