[Image 1] Chick ectopic limb. An FGF-4-soaked bead was implanted at stage 14. The embryo was fixed four days later, and stained with alcian blue to reveal the developing cartilage of the skeleton. An ectopic limb can be seen developing next to the normal forelimb, and the bead is still present in the body wall.

This is FRAKKING awesome.
