Pattern formation of the developing vertebrate limb is mainly controlled by the zone of polarizing activity (ZPA) and the apical ectodermal ridge (AER) which may act as sources of diffusing morphogens. These sources are tightly interconnected and maintained by positive feedback and, together with th

We propose a model mechanism for the initiation and spatial positioning of teeth primordia in the alligator, Alligator mississippiensis. Detailed embryological studies by Westergaard & Ferguson (1986, 1987, 1990) show that jaw growth plays a crucial role in the developmental patterning of the tooth
We propose a mathematical model mechanism for the initiation and spatial positioning of tooth primordia in the alligator, Alligator mississippiensis. Our goal is to formulate and analyse a model that explains the spatial patterning of teeth primordia. In line with experimental evidence, jaw growth p
