WormMine: ExpressionPattern Expr1270

• Pattern: The reporter genes are detectable in the adult in the body wall muscle cells, in the pharyngeal muscle cells, in the sex-specific muscle cells (e.g., vulval muscles in hermaphrodites and diagonal muscles of the male tail) and in the anal muscles. Expression is also found in the embryos at the comma to two-fold stage, when muscle lattices are being assembled. beta-galactosidase staining from the lacZ fusion is detected in a small number of cells slightly earlier in development but the identity of these cells has not yet been determined. Expression is not seen in the gonads.

	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 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
