The two primary challenges in nerve regeneration are firstly to induce nerve tissue to regrow at all, and secondly to find a way to deal with the blockade of scarring that forms around injury sites. The existence of this scar tissue is why it is the case that some progress has been made in treatment for recent nerve injury, but very little can yet be done for patients with older injuries. In that context, the recent research results noted here are exciting, an advance that offers tangible hope to the many people who presently live with loss of function due to severed or damaged nerves. This is still very early stage work, however, and we all know that it takes long years to move from initial demonstrations in animal models to clinical trials to general availability.
Regeneration of the spinal cord has been a heavily advocated and well funded goal for as long as Fight Aging! has existed. Those us of a certain age no doubt recall the Christopher & Dana Reeve Foundation in the period in which its principals were more vocal and present in the media, in the early days of high hopes for stem cell research, and prior
