• Primary Identifier: Expr1579
• Remark: The expression of pha-1::lacZ with additional 2kb of 5'UTR showed identical expression pattern.
• Pattern: The first expression of the pha-1:lacZ hybrid gene is detectable at the 100 cell stage of embryogenesis (130 minutes of embryonic development; all developmental times refer to time after the first cleavage at 20 degree) in cells that have positions in the embryo corresponding to the pharyngeal and body wall muscle precursors. Expression of the pha-1:lacZ hybrid gene at around 200 minutes of development is detected in about 25 cells that form a cylinder in the anterior part of the embryo. These pha-1:lacZ expressing cells are the pharyngeal precursors. The lineage of most of these cells (26 of 27) is restricted to pharyngeal fate and only the MSaaaaa cell produces pharyngeal cells and non-pharyngeal cells (two neurons of the ring ganglion). As soon as these 27 pharynx precursor cells divide (230-250 minutes), expression of the pha-1:lacZ gene in the pharyngeal precursors ceases and only a few cells in the presumptive pharynx region express the hybrid protein. At 420 minutes of development (2 fold stage) no pha-1:lacZ gene expression in the pharyngeal precursor cells is detectable. pha-1:lacZ expression was also observed in body wall muscle cell precursors. Expression of the pha-1 hybrid protein starts early in all body wall muscle cell precursors and is detectable throughout embryonic development in these cells.

• Primary Identifier: Expr569
• Remark: 50-70 cell embryo(author) = 51-cell embryo(curator). No maternal RNA.
• Pattern: Staining in body muscle precursors at 60-cell through bean embryo.

• Primary Identifier: Expr1472
• Remark: Reporter gene fusion type not specified. T14G12.4 = fkh-2
• Pattern: expression was observed in the descendants of the D founder cell. T14G12.4::gfp expression was also detected in many other cells more anteriorly that probably overlap with, but are not identical to, those of the AB founder cell lineage that express the pes-1::gfp fusion gene.

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 390-420min 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 looks like a comma. A stage between bean embryo and 1.5-fold embryo.		comma embryo Ce	WBls:0000017
	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

	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
