Fig. 2. Cut was downregulated by Notch signaling in follicle cells that undergo
endoreplication. Mutant cells are marked by the lack of GFP (green in A-D).
Cut staining is shown in red in A-D and in white in A'-D'. DAPI is
shown in blue in A. (A) Follicle cells surrounding a Dl germline
clone continued to express Cut in a stage 8 egg chamber. (B-D) Notch
(B,B'), psn (C,C'), or Su(H) (D,D')
follicle-cell clones (outlined) caused Cut to be continuously expressed in the
mutant clones beyond stage 6 in a cell-autonomous manner.
