WormMine: ExpressionPattern Expr1567

• Pattern: The transcript was detectable right before elongation, through the comma stage, and until the 1.5 fold or 2 fold stages. No transcript was detected from one cell stage to just before this time. No transcript was detected after the 2-fold stage. This was not due to poor penetration of the probe into the late stage embryos because a control probe with myo-2 anti-sense probe showed clear signal. The hch-1 expressing cells probably are hypodermal cells. The signal is localized first in the dorsal and lateral surface area of the middle and posterior region of the embryos. At later stages, the signal is restricted to lateral surface regions, probably hypodermal seam cells.

	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 420-460min 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 fold back 50%. A stage between comma embryo and 2-fold embryo.		1.5-fold embryo Ce	WBls:0000018
	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
