Summary:
A study led by a researcher at the University of Southern California has found a new model to explain how signals between cells in the embryo control limb development. The study, which will be published in the May issue of the journal Nature and now available online, found that secreted growth factors at the distal tip of the embryonic limb act as instructive molecules that control the pattern of bones along the length of the limb in an animal model.
