Fig. 3. Extra-embryonic membranes. Staged A. gambiae embryos were
analyzed by scanning electron microscopy (A,B) and DIC
microscopy (D,E,F). (C) Lateral view of D.
melanogaster embryo at the end of germband extension stage; the
amnioserosa is indicated by the white arrow. The embryos in the left panels
are at the same relative stages as those shown in the right panels. The same
embryo is shown in E and F, and was colored in F to better visualize the
separate amnion (red) and serosa layers (blue). The embryos in D-F were
hybridized with an eve RNA probe. Blue arrows indicate the serosa,
red arrows indicate the amnion.
