WormMine: ExpressionPattern Expr2568

• Pattern: When GFP-fused Cedna2 gene was expressed in C. elegans under control of its own promoter, GFP appeared at the 100 cell stage, persisted through the 400 cell stage, and then disappeared at the comma stage. During larval growth, Dna2 expression appeared again at the L3 stage, and was observed to localize in the somatic cells of the spermathecae and uterus at the L4 stage. Expression of GFP-Dna2 was not detected in any somatic cells of adult worms.
• Primary Identifier: Expr2568
• Remark: Reporter gene fusion type not specified.

	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 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
