WormMine: ExpressionPattern Expr23

• Pattern: About 6 nuclei in the major nerve ring are seen from hatching onwards. The number decreases to 4 by the onset of adulthood. Up to 8 neural nuclei of the head ganglia stain from the pre-hatched embryo stage to adulthood, a few of the cells also showing axonal process staining. Pre-hatched worms also harbour staining at the pharyngeal lumen.
• Primary Identifier: Expr23
• Remark: pre-hatched embryo(author) = fully-elongated embryo(curator).

	The stage that begins when a C.elegans individual is fully-developed and has reached maturity.		adult Ce	WBls:0000041
	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
