Figure 5From: Optix defines a neuroepithelial compartment in the optic lobe of the Drosophila brainOptix represses Vsx1 expression. (A-B”) Anterior views of late third instar larval brains. Optix misexpression in the VsxGAL4 neuroepithelial domain represses Vsx1 expression. Cells outlined by Dlg (blue), Optix protein in green, Vsx1 in red. (B”) Vsx1 expression is observed in neurons (orange star) but not in neuroepithelial precursors (yellow arrowhead).Back to article page
