As such, purified recombinant MAG was found to block neurite outgrowth as well as induce growth cone retraction [52, 75].
In neuronal growth cone the link (clutch) involves the immunoglobulin superfamily cell adhesion molecule [15] or the L1 cell adhesion molecule [16].
If conditions are favorable, the retraction bulb is transformed in a growth cone, a dynamic structure, which extends and guides the regenerating axon towards its target.
At the end of each neurite is a growth cone where structural proteins are assembled to form the cell membrane.

On the other hand, studies have demonstrated that GSK-3[beta] phosphorylation of the CRMP-2 T509 site can play a crucial role in mediating the repulsive action of Sema3A [85]and promoting growth cone collapse [77].
Neurons were plated between grooves scored onto the cell culture dish to restrict neurite outgrowth and facilitate growth cone interactions with muscle fibers (Fig.
