WormMine: ExpressionPattern Expr14755

• Pattern: In early larvae, this reporter was expressed in a cluster of posterior cells including rectal epithelial cells, the overlying dorsal and ventral body wall muscles, the stomatointestinal muscles, the anal depressor muscle, and P11/12, along with weak expression in several head neurons, which is largely consistent with smFISH data on egl-20 transcript localization (Harterink et al., 2011a) and previous transgenes (Whangbo and Kenyon, 1999). This reporter also labeled several posterior neurons and their projections along the ventral nerve cord that terminated in the nerve ring. Tagged Wnt protein clearly localized near reporter-labeled axons in the head.

a single, H-shaped cell which lies just above the anus and connects the roof of the anal canal to the dorsal bodywall; its contractions act to increase the size of the anal opening by lifting the roof of the rectum and hence facilitate expulsion of intestinal contents.	anal depressor muscle	dilator muscle	WBbt:0004292

These cells include: B, F, Y, U, K' and K. All rectal epithelial cells contain secretory membrane stacks along this region facing the lumenal cuticle and produce some portion of the cuticular lining of the rectum. These are interfacial cells that connect the alimentary system to the main body syncytium.	rectal epithelial cell	rectal epithelium	WBbt:0008182
