Figure Caption
Fig. 3 Alcian blue staining of 6 dpf old zebrafish embryos shows that chondrocyte differentiation and proliferation are unaffected by the loss of Hedgehog signalling after 72 hpf. (A, C and E) show the EtOH treated control fish. (B, D and F) show embryos treated with cyclopamine. There in no change in patterning or differentiation of the cartilage skeleton at the time points investigated as judged by morphology. (G) shown the quantification of the number of chondrocytes in the ceratohyal from the experiments shown in (A–F). Please see Fig. 2 for abbreviations and notes.
