Figure 4

High resolution images of the interface between the lateral epidermis and the amnioserosa in an embryo expressing GFP-zip∕MyoII heavy chain is shown before (A) and after (B) a spaceship cut. The “bars on a string” pattern is apparent in both native and secondary purse strings. Arrows in A and B depict regions with particularly conspicuous bars on a string pattern. Scale bar in A is for both panels and is 10 μm.
