How embryos scale vertebrae

As embryos develop and grow, from a single-cell egg to a fully functional body, they must form organs that are in proportion to the overall size of the embryo. The exact mechanism underlying this fundamental characteristic, called scaling, is still unclear. But researchers from the European Molecular Biology Laboratory in Heidelberg, Germany, and McGill University in Montreal are one step closer to understanding it.
