Fig. 7. Drosophila misshapen is required in marginal cells of the epidermis for actin and myosin 2 localization and cell constriction. Phalloidin (A,D,G), anti-myosin 2 (B,E,H) and anti-Armadillo (C,F,I) staining of control embryos (A-C) and embryos expressing DN-msn (D-I). e22c-Gal4 (D-F) and LE-Gal4 (G-I) were used to express DN-msn in the whole epidermis or in marginal cells of the epidermis, respectively. (E,F) and (H,I) show myosin 2/Armadillo co-staining. Arrowheads point at areas of disrupted myosin 2 staining correlating with abnormally wide cell shape. Scale bar: 10 µm.
