WormMine: ExpressionPattern Expr8005

• Pattern: During mid-embryogenesis, ZEN-4::GFP is expressed in all dividing cells, consistent with its role in cell division. However, at the onset of dorsal intercalation, when epidermal precursors have ceased dividing, ZEN-4::GFP becomes undetectable in the epidermis. ZEN-4::GFP is expressed for a correspondingly longer period, and is visible in spindle mid-bodies as ventral enclosure begins and before it completes. By the end of enclosure, little or no ZEN::GFP is detectable. As elongation of the embryo begins, virtually no ZEN-4::GFP can be detected, although occasional bright spots can be observed. By the 1.5- to 2-fold stage of elongation, no ZEN-4::GFP can be detected.
• Primary Identifier: Expr8005
• Remark: Picture: Figure 2. Similar results were obtained using an anti-ZEN-4 antibody.

	The C. elegans life stage spanning 0-350min after first cleavage at 20 Centigrade. Proliferate from 1 cell to 560 cells. From start of first cleavage until cleavage is over.		proliferating embryo Ce	WBls:0000004
	The C. elegans life stage spanning 350-390min 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. Emrbyo elongation started but have not formed comma shape yet. The shape of embryo looks like a lima bean. A stage right before comma embryo. Also called lima embryo or lima bean stage.		bean embryo Ce	WBls:0000016
