Expression of type I and III collagens and fibronectin after transection of rat sciatic nerve. Reinnervation compared with denervation.

Abstract

During peripheral nerve regeneration the expression of the extracellular matrix genes does not seem to be simply related to the presence of axons. Endoneurial fibroblasts contribute to the production of collagen type I and apparently to that of fibronectin, which thus is not totally derived from plasma.
