WormMine: ExpressionPattern Expr2608

• Pattern: A 10 kb genomic promoter sequence is also expressed in vulval cells, which may not reflect the natural expression pattern of the ceh-2 gene, as that promoter extends into the next gene upstream. Reporter gene expression under the control of the ceh-2 promoter is detected shortly after formation of the pharynx primordium, and is strongest in elongated embryos and early larvae. 1.6 kb sequence upstream from the start codon drives expression only in the neurons (pTRB201); a fourth exon gfp fusion that includes 4.5 kb of upstream sequence and the large intron within the homeodomain is expressed also in e2 and m2 cells (pTRB202).
• Primary Identifier: Expr2608
• Remark: Reporter gene fusion type not specified.

	The stage that begins when a C.elegans individual is fully-developed and has reached maturity.		adult Ce	WBls:0000041
	The third stage larva. At 25 Centigrade, it ranges 32.5-40 hours after fertilization, 18.5-26 hours after hatch.		L3 larva Ce	WBls:0000035
	The second stage larva. At 25 Centigrade, it ranges 25.5-32.5 hours after fertilization, 11.5-18.5 hours after hatch.		L2 larva Ce	WBls:0000027
	The fourth stage larva. At 25 Centigrade, it ranges 40-49.5 hours after fertilization, 26-35.5 hours after hatch.		L4 larva Ce	WBls:0000038
	The first stage larva. At 25 Centigrade, it ranges 14-25.5 hours after fertilization, 0-11.5 hours after hatch.		L1 larva Ce	WBls:0000024
	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. Also called pre-hatched embryo, late embryo or morphogenetic embryo.		fully-elongated embryo Ce	WBls:0000021
	The C. elegans life stage spanning 350-620min 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 stage that embryo starts elongation until elongation is over.		elongating embryo Ce	WBls:0000015
	The C. elegans life stage spanning 290-350min after first cleavage at 20 Centigrade. Proliferate from 421 cells to 560 cells. The stage when embryo just finished gastrulation and is enclosing.		enclosing embryo Ce	WBls:0000013
