Fig. 2. R06F6.1::gfp is expressed in all somatic cells throughout development. (A) Confocal Z-series projection of an embryo approximately 300 minutes after the first cell division. (B) An epifluorescent image of the expression of R06F6.1::GFP in an L2 larva. The actively dividing nuclei of the lateral hypodermal cells are indicated by arrowheads, and an intestinal nucleus (which undergoes endoreduplication during postembryonic development) is indicated by an arrow. These cells show stronger GFP expression than non-dividing cells. (C) Epifluorescence image showing that nuclei of recently divided cells strongly express R06F6.1::GFP. The cells that form the postdeirid (boxed) and two lateral hypodermal cells (arrows) show stronger expression than neighbouring cells. Scale bars represent 10 µm.
