WormMine: ExpressionPattern Expr14320

• 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 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
