Glial-Secreted Netrins Regulate Robo1/Rac1-Cdc42 Signaling Threshold Levels during Drosophila Asymmetric Neural Stem/Progenitor Cell Division

Investigators showed that the extrinsic axon guidance cues Netrins, secreted by a glial niche surrounding larval brain neural stem cell lineages, regulated neuroblast asymmetric stem cell division.
