Fig. 4 Expression of shh, axl, and nk2.2 in the ventral brain is impaired by ethanol treatment. (A to C) Expression of shh in control embryo (A) and ethanol-treated embryos (B, C). (D to F) Expression of axl in control embryo (D) and ethanol-treated embryos (E, F). (G to I) Expression of nk2.2 in control (G) and ethanol-treated embryos (H, I). Embryos are at the 24-h stage. Arrowheads in A to C indicate the positions of the mid-hindbrain boundary. Orientation of embryos is anterior to the left and dorsal up.
