WormMine: ExpressionPattern Expr15860

• Pattern: We found that blmp-1 transcription is detected in the tail-spike cell as early as the mKatePH reporter (1.5-fold stage). blmp-1 transcription continues until the tail-spike cell dies with a characteristic rounded refractile morphology at the 3.7-fold stage.

	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 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
