Table 1.

Expression of dkk1 in epithelium and mesenchyme of first-generation teeth (3V¹, 4V¹, and 5V¹) and their successors (3V², 4V², and 5V²) between 48 and 152 hpf.

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.
