Fig. 2: Every cell has a sexual identity.

a Expression pattern of cell-type specific reporters in the female midgut at the third larval stage (DNA labelled with DAPI, blue; the nuclear form of GFP, green). b Expression pattern of cell-type specific reporters, combined with the traF-LexA marker, in the female midgut at the third larval stage (DNA labelled with DAPI, blue; the nuclear form of GFP, green, the nuclear form of tdTomato, red). Arrowheads indicate examples of cells expressing both GFP and tdTomato. c Expression pattern of cell-type specific reporters, combined with the dsx-Gal80 and fru-Gal80 repressors, in the female midgut at the third larval stage (DNA labelled with DAPI, blue; the nuclear form of GFP, green). The visualised cell populations and specific cell types are yellow or green in the right and top diagrams. The TraF-expressing cells alone and co-expressing cell-type specific markers are depicted in red and yellow, respectively. Diagrams of the alleles used are presented on the top of each panel. Immunohistochemical analyses were repeated at least three independent times.
