a) Experimental schematic. The embryo sits on the xy stage of an inverted microscope. A programmed displacement of a glass micropipette attached to an xyz controller generates a force in the plane of the embryo. We capture the image using a CCD camera attached to the microscope. b) Image of an embryo showing the axis definitions and the points of force application. During the experiments we applied AP force either at the center or at the side of the embryo, in the middle of the area pellucida, as indicated by the arrows. Even though we use a hollow pipette, there is no suction applied to the tissue; it used as a force probe in the horizontal xy plane, and is inserted 50 μm into the tissue.
