Growth cones facilitate the growth and guidance of axons by bundling and extending actin filaments into structures known as filopodia and microspikes. Binding of filopodia and adhesion receptors to particular extracellular matrix (ECM) components or ligands is translated into actin filament assembly, cytoskeleton remodeling and force-driven motility. These events culminate in the growth of the neuron towards its target… Read more…
