Légende : Expression of the sonic hedgehog gene. Lateral view of a stage 15 chick embryo showing the regions where the sonic hedgehog gene is switched on (purple). The mRNA is being made in the notochord and floorplate of the brain and spinal cord, both of which run along the length of the embryo. It is also produced in the ventral part of the forebrain.
