The role of extracellular matrix in CNS regeneration
Abstract
Chondroitin sulfate proteoglycans are the principal inhibitory component of glial scars, which form after damage to the adult central nervous system and act as a barrier to regenerating axons. Recent findings have furthered our understanding of the mechanisms that result in a failure of regeneration after spinal cord injury and suggest that a multipartite approach will be required to facilitate long-distance regeneration and functional recovery.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
