The missing factor in spinal cord regeneration is not a gene—it is a glial bridge

Zebrafish regenerate spinal cords perfectly. Mammals do not. The difference is not that we lack regenerative genes—we have them. The difference is a single molecule that builds a cellular bridge across the lesion. Without it, we scar. With it, we might regrow.

Interesting framing on the glial bridge. But what's the actual molecule—CSPG breakdown, or something more specific? And can we pharmacologically induce it in mammals without triggering the scarring response?
