Fig. S1 Recapitulation and rescue of epiboly defects in Mxtx2 morphants. (A-D) Embryos were injected at the 1-cell stage with (A) 8 ng Ctrl MO, (B) 1 ng Mxtx2 MO, (C) 2 pg mxtx2 mRNA + 1 ng Mxtx2 MO or (D) 2 pg mxtx2 mRNA alone, and documented by time-lapse in their chorions, as previously described (Pei et al., 2007; Schroter et al., 2008). Images show embryo morphologies at the time that control embryos reached 100% epiboly. (E) A total of 159 embryos that were time-lapsed or incubated in parallel were scored, revealing a highly significant degree of rescue. ***, P<0.0001; χ2 test.
