Figure Caption

Fig. 4 CNS phenotype of ott mutants. Transverse sections through the spinal cord of 80 hpf larvae. (A–F) Myelin protein expression in wild type (A, C, E) and ott (B, D, F) mutant fish. (A, B) mbp is not expressed in ott mutants. (C, D) Plp1b is not expressed in ott mutants. (E, F) Mpz is weakly present in some grey matter cells in ott mutants. (G, H) In wild type fish, olig2-expressing cells have migrated to the periphery by 80 hpf (G) whereas olig2 expression is still restricted to the ventral ventricular zone in ott mutants (H). (I, J) The distribution of cells expressing the motor neuron marker isl1 is similar in wild type (I) and ott mutant (J) fish. (K, L) Electronmicrographs of spinal cord axons ensheathed by loosely wrapped immature myelin in wild type (K) and ott mutant (L) fish. Scale bars in panels K and L, 200 nm.
