WormMine: ExpressionPattern Expr1104

• Pattern: In situ hybridization experiments with anti-sense probe showed that the csq-1 gene began to be expressed in 2-fold-stage embryos along their mid-body lines where body-wall muscle precursor cells are located. No signal was detected in embryos earlier than the 2-fold stage, suggesting that the csq-1 gene is not expressed maternally. All the embryos in stages later than 2-fold showed csq-1 expression in their body-wall muscle precursor cells. Larvae and adult animals showed robust signals in body-wall muscle cells.
• Primary Identifier: Expr1104
• Remark: In control hybridization experiments with a sense-strand probe no signal was detected.

	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 520-620min 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 shape of embryo is elongated and tripple fold. A stage between 2-fold embryo and fully-elongated embryo. Also called pretzel embryo or pretzel stage.		3-fold embryo Ce	WBls:0000020
	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.
