Absence of p53 alleviates the cartilage phenotypes present in wu:fb16h09 and pkdcc morphants. A: Flat-mounted neurocranium of wu:fb16h09 morphant in wildtype zebrafish after injection of 10 ng ATG Morpholino. B: Flat-mounted neurocranium of wu:fb16h09 morphant in p53 null zebrafish after injection of 10 ng ATG Morpholino. (Note that the wu:fb16h09 ATG Morpholino only generates neurocranial defects and so we were not able to assess the influence of p53 on viscerocranial defects in this experiment.) C: Flat-mounted cranial cartilages of pkdcc morphant in wildtype zebrafish after injection of 20 ng ATG Morpholino. D: Flat-mounted cranial cartilages of pkdcc morphant in p53 null zebrafish after injection of 20 ng ATG Morpholino. Abbreviations as in Figure 1.
