Dye-filling of the amphid sheath glia: Implications for the functional relationship between sensory neurons and glia in Caenorhabditis elegans

► DiI-staining in the amphid sheath cells in Caenorhabditis elegans. ► DiI-uptake by the amphid sheath cells correlates with DiI-filling in the amphid sensory neurons. ► Localization of F52E1.2SP::YFP expressed in the amphid sheath cell endings is abnormal in mutants defective in the amphid socket (che-14), the amphid sheath (daf-6), or cilia (che-2).
