Figure 1 Squint expression and blastomere ablation in zebrafish embryos. (A) Expression of maternal squint mRNA (green) at 1-cell and 8-cell stages and zygotic squint mRNA at high and sphere stages (d: dorsal). (B) Ablation of squint mRNA-containing blastomeres results in embryos that are ventralized or have anterior and posterior truncations. Ablation of blastomeres that do not contain squint mRNA does not affect embryonic patterning.
