WormMine: ExpressionPattern Expr13008

• Pattern: A let-653 promoter::GFP transcriptional reporter was expressed in external (cuticle-producing) epithelial cells, including the epidermis, vulva, rectum and excretory duct and pore, but was mostly excluded from internal epithelia such as the pharynx, intestine and excretory canal cell. Occasionally, let-653pro::GFP expression was observed in the canal cells of embryos, but this expression disappeared in later stages LET-653 fusion proteins were never observed in the canal cell.
• Primary Identifier: Expr13008

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
