The enamel knot is frequently associated with an enamel cord. It is formed in the cap stage and undergoes apoptosis in the bell stage. See more The enamel knot is a signaling center of the tooth that provides positional information for tooth morphogenesis and regulates the growth of tooth cusps. The enamel knot produces a range of molecular signals … See more The primary enamel knot forms at the tip of the bud during the cap stage of tooth development. This primary enamel knot undergoes apoptosis and disappears. Later, secondary enamel knots appear that regulate the formation of the future cusps of the teeth. See more
