WormMine: ExpressionPattern Expr7522

• Pattern: Expression is seen in 3 cells in the terminal bulb of the pharynx and in the junction between the pharynx and intestine, late embryo onwards, weakening through the larval stages. There is also expression in the developing gonad, possibly the spermathecae. However, all the expression is quite weak.
• Primary Identifier: Expr7522

A group of six equivalent cells forms a tightly constructed `valve` that links the posterior bulb of the pharynx to the anterior four cells of the intestine. These six cells comprise a small epithelial channel with a cuticular lining in continuity with the pharyngeal cuticle and link the lumen of the pharynx to the large lumen of the anterior intestine.	pharyngeal-intestinal valve	cardia	WBbt:0005767

	The C. elegans life stage spanning 620-800min(hatch) after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. A stage after elongation is over. The last stage of embryogenesis.
