Fig. 5

Gene expression patterns during dermal scale development in the catshark Scyliorhinus canicula. Whole-mount hybridized tails of about 3 cm long embryos (a–g) and transverse sections showing tissue specific expression in scale buds at stage EM (a1–g1), LM (a2–g2), ED (a3–g3) and LD (a4–g4). Gene names are indicated of the left side of each panel, same legends as Figs. 3 and 4. Scale bars: (a–g) 200 μm, (a1–g4) 50 μm
