WormMine: ExpressionPattern Expr14319

• Pattern: hlh-4 expression is not observed in any blast cells during embryonic or postembryonic development but rather is first expressed in two pairs of postmitotic cells in the precomma stage embryo, shortly after their birth. One pair is the ADL neurons and the other pair is the sisters of ADL, which die shortly after their birth by programmed cell death. Expression of hlh-4 in ADL is observed for the remainder of embryogenesis, continues during larval and adult stages, and is never observed in any other cell throughout the entire organism. The ADL-specific fosmid-based reporter expression pattern is recapitulated by a 700-bp 5' promoter fusion reporter.

	The stage that begins when a C.elegans individual is fully-developed and has reached maturity.		adult Ce	WBls:0000041
	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
	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 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
