Embryos were injected at the one-cell stage with morpholino oligonucleotides (MOs, GeneTools) and/or mRNA. Antisense MOs were used at the following concentrations: 10 ng snai2 splice-block MO (SB MO)[15 (link),44 (link)] and 0.75 ng snai2 5’UTR MO (UTR MO). Capped mRNA was synthesized from linearized pCS2+ constructs using the mMessage mMachine SP6 Transcription Kit (ambion, AM1340), according to manufacturer’s recommendations. Full length snai2 mRNA was injected into embryos at 150 ng/μl.
