Figure 6 Phenotypic Effect of Microinjecting goosecoid or Δgsc mRNA into the Two Ventral Blastomeres at the 4-Cell Stage (A) Δgsc control, only one dorsal lip is present at early gastrula. (B) goosecoid mRNA injection, two dorsal lip–like structures are present (arrows). (C) Top, two embryos that received goosecoid mRNA; secondary neural axes are visible. The two bottom embryos were injected with Δgsc mRNA, and no secondary axis is present. (D) Twinned embryo produced by goosecoid mRNA injection; note that a complete head structure containing eyes, hatching gland, and cement gland has been induced. Image published in: Cho KW et al.
