Fig. 6. Ectopic expression of UPD and UPD^TM induces extra migratory border cells. (A-G) Confocal immunofluorescence images of egg chambers stained with anti-GFP to detect those cells expressing UAS-UPD (green) and those expressing STAT (red). (A-C) HS-FLP-GFP; UAS-upd egg chamber and (D-F) HS-FLP-GFP; UAS-upd^TM egg chamber. (G) An example of the ectopic border cells that surround the cell expressing UAS-upd^TM. Arrows indicate normal border cell clusters; arrowheads indicate ectopic border cell clusters. Scale bars: in A, 50 µM for A-F; in G, 10 µM.
