Growth cones navigate by coupling extracellular guidance cues to directed outgrowth of the actin cytoskeleton through cyclical extension of filopodia and lamellipodia, but the biochemical basis of this coupling is at present unknown. Recent studies have shown that members of the Rho family of small GTPases regulate the formation of filopodia, lamellipodia and stress fibres in fibroblasts, and there are striking morphological similarities between spreading fibroblasts and advancing growth cones. This resemblance suggests that the Rho family of proteins could be the link between incoming signals and the regulation of both actin dynamics and cell-substratum adhesion in the neuronal growth cone.

Abstract

Growth cones navigate by coupling extracellular guidance cues to directed outgrowth of the actin cytoskeleton through cyclical extension of filopodia and lamellipodia, but the biochemical basis of this coupling is at present unknown. Recent studies have shown that members of the Rho family of small GTPases regulate the formation of filopodia, lamellipodia and stress fibres in fibroblasts, and there are striking morphological similarities between spreading fibroblasts and advancing growth cones. This resemblance suggests that the Rho family of proteins could be the link between incoming signals and the regulation of both actin dynamics and cell-substratum adhesion in the neuronal growth cone.
