The loxl3b morphant phenotype is not caused by p53-mediated cell death. A-C: Light microscopic images of 72 hpf embryos injected with control (A), 4 ng MO2 (B), or 2 ng P53MO and 4 ng MO2 (C) morpholino. D-F: Alcian blue staining of ventral cartilages from 72 hpf embryos injected with control (D), MO2 (E), or P53MO and MO2 (F). G-I: Alcian blue staining of dorsal cartilages from 120 hpf embryos injected with control (G), MO2 (H), or P53MO and MO2(I). J-L: Acridine orange staining in 30 and 48 hpf embryos in control (J) and P53MO and MO2 injected embryos (K, L). Corresponding images of sox10:rfp embryos are included for comparison (N, O). M: Quantification of number of affected embryos in wild-type and p53-/- embryos injected with control, MO2 or P53MO.
