  • Title: Deciphering skeletal patterning: clues from the limb.
    Author: Mariani FV, Martin GR.
    Journal: Nature; 2003 May 15; 423(6937):319-25. PubMed ID: 12748649.
    Abstract:
    Even young children can distinguish a Tyrannosaurus rex from a Brontosaurus by observing differences in bone size, shape, number and arrangement, that is, skeletal pattern. But despite our extensive knowledge about cartilage and bone formation per se, it is still largely a mystery how skeletal pattern is established. Much of what we do know has been learned from studying limb development in chicken and mouse embryos. Based on the data from such studies, models for how limb skeletal pattern is established have been proposed and continue to be hotly debated.
