WormMine: ExpressionPattern Expr11811

• Pattern: The distal enhancer activated reporter gene expression both inside and outside the pharynx. In larvae and adults, expression was observed in the m3, m4, m5, and m7 pharyngeal muscles as well as pharyngeal marginal cells, epithelial cells, and neurons. Expression was also observed outside the pharynx in the body wall muscles and the ventral nerve cord. Distal enhancer activity initiated in the pharynx at the bean stage of embryogenesis near the time that the endogenous ceh-22 gene is first expressed.

• Remark: Feature: 'WBsf919537::pPD95.21'

	The stage that begins when a C.elegans individual is fully-developed and has reached maturity.		adult Ce	WBls:0000041
	A developmental life stage of the nematode Caenorhabditis elegans that occurs from egg hatching until adulthood.		larva Ce	WBls:0000023
	The C. elegans life stage spanning 390-420min 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. The shape of embryo looks like a comma. A stage between bean embryo and 1.5-fold embryo.		comma embryo Ce	WBls:0000017
	The C. elegans life stage spanning 460-520min 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. The shape of embryo is elongated and double fold. A stage between 1.5-fold embryo and 3-fold embryo.		2-fold embryo Ce	WBls:0000019
	The C. elegans life stage spanning 520-620min 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. The shape of embryo is elongated and tripple fold. A stage between 2-fold embryo and fully-elongated embryo. Also called pretzel embryo or pretzel stage.		3-fold embryo Ce	WBls:0000020
	The C. elegans life stage spanning 420-460min 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. The shape of embryo is elongated and fold back 50%. A stage between comma embryo and 2-fold embryo.		1.5-fold embryo Ce	WBls:0000018
	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
