Retinal dysfunction is often caused by aberrant neural cell migration during development. In this study, we observed the migration of neural cells of the Drosophila melanogaster after marking cells of the 3rd instar larvae with the GAL4-UAS expression system when exposed to a concentration gradient of FGF-8 through the use of a microfluidic device. The glial and neuronal cell ratio in the developing brain was determined through immunofluorescent staining and observation. In future studies, a microfluidic device that mimics the developing Drosophila brain and retina will be designed in order to better understand the biological factors that affect the migration and differentiation of the cells.
