Fig. 3. Profile of actin-GFP and tau-lacZ in third instar larval peripheral glia. (A) Fluorescence of actin-GFP in peripheral glial processes. The actin-GFP distribution is mesh-like with dense concentrations interspersed (arrow). The image was collected from a live third instar larva using a disk scanning confocal microscope. (B) Tau-lacZ (green) and anti-HRP staining (red) to show peripheral glial microtubule network and peripheral neurons, respectively. The glial microtubule network consists of long, rope-like structures (arrow) extending along the length of the cell. The image was collected on a laser-scanning confocal microscope.
