Some of our organs, like liver or heart, are lateral. On the contrary, our body builds up following an axial symmetry, visible through the spinal column. A new molecular cascade occuring in this symmetry of vertebrates, has just been discovered by the French-American team led by Olivier Pourquié, and recently arrived at the IGBMC. These results have been published in Nature.
