After CNS trauma a sheet-like, collagen type IV (Coll IV) immunopositive basement membrane (BM) develops in the lesion zone as well as at newly formed blood vessels. The basic scaffold of this BM is composed of Coll IV, laminin and nidogen but numerous other proteins some of which are discussed to be inhibitory for axonal regeneration, i.e. chondroitin- and heparansufate-proteoglycans, are associated with BM. This review will focus on the collagenous wound healing scar, discuss its composition and summarize the experimental results that demonstrate its role in the failure of axonal regeneration in the injured mammalian CNS.
