Abstract

Chondroitin sulphate proteoglycans (CSPGs) are one of the major families of inhibitory extracellular matrix molecules in the central nervous system. The expression of various CSPGs is strong during early nervous system development; however, it is downregulated during maturation and up-regulated again after nervous system injury. In vivo injection of an enzyme called chondroitinase ABC, which removes the inhibitory chondroitin sulphate chains on the CSPGs, in the injured area promotes both the regeneration and plasticity of the neurons. Here, we describe the method of in vivo injection of the chondroitinase ABC into the cortex of adult rat brain and the histochemical method to assess the successfulness of the digestion.
