Astrocyte morphology is controlled by neuron-derived FGF.
Abstract
The highly ramified processes of astrocytes enable cellular interactions and extracellular homeostasis. In this issue of Neuron, Stork et al. (2014) report that extension and elaboration of astrocyte processes in Drosophila is controlled by the release of FGF by neurons.
