Abstract
Chondroitin sulfate proteoglycan (CS-PG) was purified from rat brain and examined for its effect on neurite outgrowth in primary cultures of embryonic rat neocortical neurons. Neurite outgrowth was increased in culture wells coated with CS-PG. The core protein and glycosaminoglycan (GAG) prepared from the CS-PG were also examined for neurite-promoting activity. The activity was observed in culture wells coated with the core protein but not with GAG. These results suggest that CS-PG stimulates neurite outgrowth from the cultured neurons via its core protein.
