WormMine: ExpressionPattern Expr11274

• Pattern: The most upstream located 450 bp (enh450) of enh3.4 were sufficient to drive most aspects of the normal ceh-13 expression pattern in comma-stage embryos. enh450 was able to drive GFP expression in dorsal body wall muscle cells and cells of the future VNC. Interestingly, the strong endodermal expression observed with enh740 was not induced by these constructs, suggesting that enh740 and enh450 are responsible for different aspects of ceh-13 expression during the comma stage. The most important difference between enh740 and enh450, however, is that early embryonic GFP expression induced by enh740, could not be detected with the two enh450-containing constructs.

	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
