Table 1.
Stages of tooth development are identified as initiation and morphogenesis (I/M), early cytodifferentiation (ED), late cytodifferentiation (LD) and attached tooth (AT), in agreement with Figure 2. Level of expression is scored from – (no expression) to +++ (very strong expression). Letters following a signal refer to Figure 3 (A–F) where the tooth is visualized, so that a particular expression signal in the Table can be compared with a specific image in Figure 3.
