From: The abdomen of Drosophila: does planar cell polarity orient the neurons of mechanosensory bristles?
A UAS.fz-expressing clone affects bristle polarisation. Using young adults, neurons were stained with 22C10 antibody (green) and this image and a DIC image were combined. A UAS.fz clone was induced in the anterior domain of the A compartment. The clone is marked with the yellow marker that can be identified by the light colour of the bristles. Wild-type hairs and bristles that localize anterior to the yellow bristle (y-) have reversed polarity. These reversed bristles are localized in the anterior zone of the compartment, yet their dendrites (white arrows) are straight (no U-shape) and the somata of the neurons (n) are posterior to the bristles. The y- bristle is also in the anterior zone but has lateral polarity; its dendrite (white arrow) makes a small U-shaped turn. Nevertheless, all axons (red arrow) grow posteriorly towards the nerve as they normally do.
