View source for File:Mechanims of patterning the digits on the posterior to anterior axis of the limb bud by sonic hedgehog.jpg

Diagram representing the different regions of the limb bud that will differentiate into the digits. The different colours represent varying mechanisms by which sonic hedgehog acts on the cells in the limb bud to identify them as certain digits. The level of concentration of sonic hedgehog in this case is similar to a gradient going along the posterior to anterior axis of the limb bud.
