WormMine: ExpressionPattern Expr9342

• Pattern: lin-44 was mostly localized to the posterior half of L1 larvae, in a pattern that was already present at the comma stage of embryonic development. lin-44 transcripts were present in the tail hypodermal cells hyp8, hyp9, hyp10 and hyp11, and at later larval stages in the phasmid socket cells PHso1 and PHso2 as previously reported (Herman et al., 1995). In addition, it was found that lin-44 is expressed in the rectal epithelial cells B and Y, demonstrating that lin-44 has a more anterior expression domain than has been observed using reporter transgenes.
• Primary Identifier: Expr9342

	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 520-620min 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 shape of embryo is elongated and tripple fold. A stage between 2-fold embryo and fully-elongated embryo. Also called pretzel embryo or pretzel stage.		3-fold embryo Ce	WBls:0000020
	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 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
