WormMine: ExpressionPattern Expr14756

• Pattern: We first observed tagged Wnt/EGL-20 fluorescence in posterior cells in comma-stage embryos along with isolated punctae in more anterior regions and found that tagged Wnt spread from the posterior to the mid-body region of the embryo within 60 min . In early larvae, tagged Wnt/EGL-20 formed an anteroposterior gradient along approximately the posterior half of the worm with low levels of protein detectable along the entire body axis. Tagged Wnt localized most conspicuously to posterior cells near its source along with longitudinal body wall muscles, epithelial seam cells, neuroblasts, and ventral midline cells.

Remark	Definition	Other Name	Public Name	Primary Identifier
	A developmental life stage of the nematode Caenorhabditis elegans that occurs from egg hatching until adulthood.		larva Ce	WBls:0000023
	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
