Fig. 2. CEPsh glia are required for CEP neuron dendrite extension. (A) Merged DIC/fluorescence and (B) fluorescence image of wild-type (WT) adult C. elegans expressing dat-1::GFP in CEP neurons. White and yellow arrowheads indicate dorsal and ventral left dendrite tips, respectively. (C,D) Fluorescence images of dat-1::GFP-expressing adult animals lacking either ventral (C) or dorsal (D) left CEPsh glia. (E,F) Fluorescence images of mls-2(ns156) (E) and vab-3(ns157) (F) adults, respectively, expressing dat-1::GFP. (G) Dendrite extension defects of strains of the indicated genotype. Scale bar: 5 µm.
