Identification of Neural Stem Cells in the Drosophila Larval Brain

The balance between self-renewal and differentiation must be tightly regulated in somatic stem cells to ensure proper tissue generation and to prevent tumorlike overgrowth. A Drosophila larval brain lobe consists of the central brain and the optic lobe and possesses three well-defined neural stem cell lineages that generate differentiated cells in a highly reproducible pattern. Unambiguous identification of various cell types in these stem cell lineages is pivotal for studying the regulation of neural stem cells and progenitor cells at a single-cell resolution. This chapter will describe the methodology for collection and processing of larval brains for examination by fluorescence confocal microscopy.
