Fig. 5. Distribution of nonmuscle myosin II during dorsal closure. (A-C) Lateral views of embryos before elongation of the lateral epidermis, (D-F) Lateral views of embryos during elongation of the lateral epidermis, and (G-I) Dorsal views of embryos during fusion of the lateral epidermis. Embryos were stained with an anti-myosin heavy chain antibody (A,D,G) or an anti-phospho-MRLC antibody (C,F,I). MRLC was visualized by expression of the GFP-Sqh transgene (B,E,H). Arrows indicate the leading edge of the lateral epidermis in A-F, and the dorsal midline in G-I.
