Regulation of growth cone motility
Cell Motility, 1991Nerve growth cones are the motile tips of elongating axons and dendrites. The migration and behavior of growth cones are responsible for axonal pathfinding to synaptic targets, and for the branching patterns of dendritic trees. Growth cones are studied at all levels of organization, molecular, cellular, and within intact embryos. Preparations of growth

Growth cones are the specialized tips of neuronal axons that make their way through the nervous system in search of a correct target. In his Perspective, Caroni outlines the signaling mechanisms that help steer the growth cone as it moves, and discusses a report by Song et al .

Neuronal growth cone migration
Experientia, 1990The neuronal growth cone is a semi-autonomous portion of the developing neuron that is highly specialized for motile activity. Migrating neurons may share some features with neuronal growth cones. I review some of what has been learned about growth cone initiation, the differentiation of axons and dendrites, the role of the cytoskeleton in motility ...

Growth cone responses to growth and chemotropic factors
European Journal of Neuroscience, 2008AbstractDuring nervous system development axons reach their target areas under the influence of numerous guidance cues that affect rate and direction of growth. This report addresses the unsettled question of whether and to what extent growth velocity and turning responses (attraction, repulsion) are interdependent.

Dissecting Growth Cone Guidance
Science Signaling, 2003The growth cones of developing neurons take s and turns that allow them to reach the appropriate target. Their path is guided by responses to attractive and repulsive cues from chemotropic ligands that they encounter along the way. These ligands activate receptors on the surface of the growth cone.

Microtubules and growth cone function
Journal of Neurobiology, 2003AbstractIt has been recognized for a long time that the neuronal cytoskeleton plays an important part in neurite growth and growth cone pathfinding, the mechanism by which growing axons find an appropriate route through the developing embryo to their target cells.

Microtubule organization in growth cones
Biochemical Society Transactions, 1991Neuronal growth cones guide growing axons and dendrites (neurites) through developing embryos by detecting extrinsic guidance cues and transducing the signal into changes in motile behavior. In this chapter, the role of the growth cone cytoskeleton in these events, in particular the microtubules, is discussed.

Science's STKE, 2004
The semaphorin family of guidance cues act predominantly through plexin receptors at the surface of various cell types. The small guanosine triphosphatases (GTPases) Rho and Rac have been implicated as downstream effectors of semaphorin-plexin interactions that modulate the cytoskeleton, but details of how plexins activate these GTPases ...

Autonomous regulation of growth cone filopodia
Journal of Neurobiology, 1998The fan-shaped array of filopodia is the first site of contact of a neuronal growth cone with molecules encountered during neuronal pathfinding. Filopodia are highly dynamic structures, and the "action radius" of a growth cone is strongly determined by the length and number of its filopodia.

Directional guidance of nerve growth cones
Current Opinion in Neurobiology, 2006The intricate connections of the nervous system are established, in part, by elongating axonal fibers that are directed by complex guidance systems to home in on their specific targets. The growth cone, the major motile apparatus at the tip of axons, explores its surroundings and steers the axon along a defined path to its appropriate target ...
