Fig. S1. Multicellular lateral structures in Ptp4E Ptp10D embryos expressing Rho1-CA. Green, Sas (apical membrane marker); red, Ecad (adherens junction marker). This particular embryo also expresses Egfr-DN, but similar morphologies are observed if it is not expressed. (A–C) The lateral regions of such embryos contain circular Ecad structures surrounded by apical membrane (orange line, asterisk). (D–F) A higher magnification view of the LT region. Note the blebs of apical membrane that are not associated with Ecad staining (orange lines, arrows). Scale bar: 20 µm.
