• Primary Identifier: Expr1029
• Pattern: Expression is first detected in late gastrulation by the cephalic, inner labial, and outer labial cells. As the embryo elongates and morphogenesis begins, expression in body wall muscle cells is detected by in situ hybridization and is observed by using the GFP reporter. In addition, GFP is observed in the left and right lateral ALM neurons and the anal depressor and intestinal muscle cells. As embryogenesis continues, expression in the body wall muscle declines and is not observed in the larval stages. During the larval and adult stages, GFP expression by the PLM neurons, the intestinal cells, and the distal tip cells of the gonad is observed. In addition, transient expression is observed in HSN neurons during the L3 and L4 stages and in ventral nerve cord neurons during the early L2 stage.

• Primary Identifier: Expr12934
• Pattern: PROS-1::GFP is detected in the nuclei of AMsh glia. Importantly, PROS-1::GFP is not detected in amphid sensory neurons and in the AMso glia. PROS-1::GFP is detected in many other sense organ-associated glia in the head, including the astrocyte-like CEP sheath glia, and the glia of the inner and outer labial sensilla.
