Potential for nerve regeneration?

While that is a great advance, there is no mention in the brief that there are other substantial hurdles remaining. The most significant is that of getting those growing fibers to their proper, functional targets in an adult CNS. Peripheral nerve regrowth benefits from the trail of degenerative debris that survives the original injury but, due to important histological differences, those "trails" do not exist in the CNS. Also, the transient chemical cues which worked to establish the original connections during CNS development are no longer present. Having cells sprout fibers is of little value if they cannot make the right connections. This is a much thornier issue.
