• Primary Identifier: Expr11950
• Remark: Assayed in C. elegans.
• Pattern: Expression was found consistently in hypodermal cells of all lines examined. GFP expression was particularly prominent in the hypodermal cell nuclei hyp5, hyp6, and hyp7 of the head and in the pair of hyp7 cell nuclei in the tail of adult worms. Using sensitive staining techniques for the detection of b-galactosidase activity, expression was also detected in larval stages, again strongly in the head and tail regions. The lacZ expression was less pronounced in the hypodermal cells of the body, with expression being detected in the hypodermal cell nuclei hyp4, hyp5, hyp6, and hyp7 of the head. With prolonged staining (overnight at room temperature) lacZ expression was also observed in the vulval cells of the adult, which are of hypodermal origin, in the adult body wall muscle cells, and in embryonic stages.

	From Lima bean to hatching.		Brugia late embryo	WBls:0000096
	Proliferates from 100 cells to Lima bean stage.		Brugia middle embryo	WBls:0000095
	Proliferates from 1 to 100 cells. As the Brugia female reproductive tract is long (>10 cm), it is possible to dissect it and select early embryos just by isolating early parts of the post-spermatheca uterus.		Brugia early embryo	WBls:0000094
