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

Current Opinion in Cell Biology, 1990
Although many issues remain unresolved, the past year has witnessed a number of advances in our understanding of the inter-relationships between extracellular influences, cell phenotype, growth associated proteins, second messengers, and cytoskeletal components in the control of neurite outgrowth and growth cone behavior.

Growth cone collapse is an easy and efficient test for detecting and characterizing axon guidance activities secreted or expressed by cells. It can also be used to dissect signaling pathways by axon growth inhibitors and to isolate therapeutic compounds that promote axon regeneration.

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.

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.

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.

The growth cone collapse assay has proved invaluable in detecting and purifying axonal repellents. Glycoproteins/proteins present in detergent extracts of biological tissues are incorporated into liposomes, added to growth cones in culture and changes in morphology are then assessed.

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 ...

Dynactin is essential for growth cone advance
Biochemical and Biophysical Research Communications, 2008Dynactin is a multi-subunit complex that serves as a critical cofactor of the microtubule motor cytoplasmic dynein. We previously identified dynactin in the nerve growth cone. However, the function of dynactin in the growth cone is still unclear. Here we show that dynactin in the growth cone is required for constant forward movement of the growth cone.

Sites of plasmalemmal expansion in growth cones
Developmental Brain Research, 1993Studies on plasmalemmal expansion in isolated nerve growth cones identified large, clear vesicles characteristically found in growth cones as the plasmalemmal precursor. The present article examines these plasmalemmal precursor vesicles (PPVs) in greater detail in the intact cell.
