How do the cells in a human embryo know where they are located in the body and how they should develop? Why do certain cells form a finger while others do not? Biologists have explained the mechanisms that control these steps by showing why veins form at particular points in the wing of a fruit fly. The protein Pentagone spreads a particular signal in the wing that tells the cells how to behave.
