WormMine: ExpressionPattern Expr2343

• Pattern: Expression begins as the embryo starts to elongate and continues through all larval stages and into the adult. Expression was in the anterior and became strikingly intense in larvae and adults, but the precise identity of the expressing cells has not been determined because the signal is poorly localised. The expressing cells are located outside of the pharynx, around the terminal bulb, and could include nerve cells or cells of the excretory system.
• Primary Identifier: Expr2343
• Remark: Reporter gene fusion type not specified.

	The stage that begins when a C.elegans individual is fully-developed and has reached maturity.		adult Ce	WBls:0000041
	The third stage larva. At 25 Centigrade, it ranges 32.5-40 hours after fertilization, 18.5-26 hours after hatch.		L3 larva Ce	WBls:0000035
	The second stage larva. At 25 Centigrade, it ranges 25.5-32.5 hours after fertilization, 11.5-18.5 hours after hatch.		L2 larva Ce	WBls:0000027
	The fourth stage larva. At 25 Centigrade, it ranges 40-49.5 hours after fertilization, 26-35.5 hours after hatch.		L4 larva Ce	WBls:0000038
	The first stage larva. At 25 Centigrade, it ranges 14-25.5 hours after fertilization, 0-11.5 hours after hatch.		L1 larva Ce	WBls:0000024
	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
