Gene expression patterns during late tooth development in the catshark Scyliorhinus canicula. a and b schematics of tooth bud at respectively ED and LD stage, dorsal view, labial side to the top. c schematic of histological section following section plane 1. Whole-mount dorsal views of tooth buds at ED and LD stages (d–s) and longitudinal sections following section plane 1 showing tissue specific expression (d1–s1). e2 and e3 longitudinal sections following section planes 2 and 3. Gene names are indicated of the left side of the panel, same legends as Fig. 3. Scale bars: 50 μm
