WormMine: ExpressionPattern Expr91

• Pattern: This simple pattern shows expression in the E lineage in early embryos. Staining can be seen upto 16 E cells. No expression is observed beyond comma stage embryo.
• Primary Identifier: Expr91
• Remark: early embryo(author) = proliferating embryo(curator). Other Authors "Bauer PK" "Hope IA"Date 1997-06 pre-comma embryo(author) = bean embryo(curator).

Definition	Name	Synonym	Primary Identifier
A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages.	intestine	gut	WBbt:0005772

	The whole period of embryogenesis in the nematode Caenorhabditis elegans, from the formation of an egg until hatching.		embryo Ce	WBls:0000003
	The C. elegans life stage spanning 0-350min after first cleavage at 20 Centigrade. Proliferate from 1 cell to 560 cells. From start of first cleavage until cleavage is over.		proliferating embryo Ce	WBls:0000004
	The C. elegans life stage spanning 350-390min 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. Emrbyo elongation started but have not formed comma shape yet. The shape of embryo looks like a lima bean. A stage right before comma embryo. Also called lima embryo or lima bean stage.		bean embryo Ce	WBls:0000016
