Tooth development is a dynamic process that involves the stages of the bud, the cap, and the bell, followed by root development and subsequent tooth formation. Processes such as the bud-to-cap transition are mediated by epithelial-mesenchymal interactions. In addition, the position of a cell in a developing embryo determines its fate due to the relative differences in concentration of signaling molecules and growth factors.
Scientists find cells that know when, where and how to grow teeth
