Fig. 6. Expression of the STAT target gene pointed (pnt) is affected in Chc and dor mutant cells. Expression of STAT (blue) and the activity of the JAK/STAT pathway, monitored using a pointed-lacZ reporter gene (red). Staining of wild-type (A-A''), Chc1 (B-B'') and dor8 (C-C'') egg chambers. The clonal marker is GFP (green in B-C''). Broken lines mark the mutant cells. Bar, 10 µm.
