Figure 2From: Impact of steroid hormone signals on Drosophila cell cycle during developmentWg protein, dmyc expression and cell cycle patterning in the Drosophila wing pouch. (A) Wg protein (red) is strongly expressed along the dorsal-ventral boundary of the wing pouch. (B) α-gal antibody staining (pink) of dmyc-lacZ (w67c 23P{lacW}l(1)G0354G 0354; [109]) discs shows a pattern consistent with dmyc transcription throughout the cycling cells of the pouch and downregulation of dmyc within the G1 arrested cells of the ZNC. (C) The zone of non-proliferating cells (ZNC) can be seen by the reduced BrdU staining (red) for S-phase along the dorsal-ventral boundary. Wing imaginal discs are aligned dorsal (D) to the top of the image, ventral (V) the bottom.Back to article page
