title: Glia as mediators of growth cone guidance: studies from insect nervous systems.
abstract: Growth cones experience many different cues in their journey to their final target. They can respond to a variety of attractive and repulsive cues that can be secreted or cellular. These cues are generated by a wide range of cell types. One subset of cells that play an important role in growth cone guidance are glial cells. Glia secrete guidance cues and express cellular cues on their surface that guide axonal outgrowth. In doing so, glia can act as intermediate targets in growth cone guidance, a process that is conserved between vertebrate and invertebrate nervous systems. Recent work in grasshopper, Drosophila and moth nervous system development has underscored the importance of the instructive role glia play during axonal outgrowth.
