Fig. 7. Hh signaling contributes to organization of the ommatidial array. (A-D) Scanning electron micrographs of the surface of adult eyes. (E-H) Arm staining used to show the cellular structure of pupal eyes, ~36-42 hours (E-G) or ~28 hours (H). Anomalous structures are indicated as follows: red stars for missing or duplicated cone cells; the double red star in H indicates a cone cell cluster with a round cell characteristic of apoptotic morphology; yellow stars indicate 1° cells failing to enclose cone cells; green diamonds indicate 1° cells intersecting with tertiary cells; red triangles indicate missing or misplaced bristles. (I-L) Schematics of a pupal ommatidium (see Fig. 6 legend for details). Dorsal is upwards and posterior is towards the left; genotypes are indicated under each panel.
