Organization and metamorphosis of glia in the Drosophila visual system

摘要: The visual system of Drosophila is an excellent model for determining the interactions that direct differentiation nervous system's many unique cell types. Glia are essential not only in development system, but also function those neurons with which they become associated adult. Given their role and adult we need to both accurately reliably identify different subtypes glia, relate glial larval brain previously described We viewed driver expression subsets eye disc glia through earliest stages pupal reveal counterparts these cells Two populations exist lamina, first neuropil optic lobe: arise from precursors eye-disc/optic stalk brain. In cases, a single source gives rise at least three types glia. Furthermore, analysis second neuropil, medulla, has identified four astrocyte-like (reticular) Our clarification lamina's identification origins, particularly respective contributions, begin define developmental establish
