WormMine: ExpressionPattern Expr3846

• Pattern: Larvae containing this transgene express GFP in a group of epidermal and muscle cells in the posterior near the anus. In embryos bearing this transgene, GFP fluorescence could not be detected the time when the HSNs migrate. muIs49 embryos were stained with an anti-GFP antiserum and these embryos expressed GFP in several cells of the developing tail beginning just before the comma stage and continuing throughout embryogenesis and larval development. To reveal the relationship between migrating HSNs and EGL-20-expressing cells, embryos carrying both muIs49 and muIs13 (Pegl-5::lacZ) transgenes were stained with antisera against GFP and LacZ. The Hox gene egl-5 is expressed in HSNs and a few cells in the tail. It was observed that the HSNs migrated away from the EGL-20 source.

	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 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
