Functional genomics identifies neural stem cell sub-type expression profiles and genes regulating neuroblast homeostasis

► Genetically different ectopic neuroblasts have similar expression profiles. ► Very few transcriptional differences separate type I/II neuroblasts. ► Loss of function screen identifies neuroblast self-renewal/homeostasis genes. ► Differentially expressed neuroblast and neuron genes identified. ► Expression profiling dataset provides neuroblast/neuron gene resource.
