Fig. 5. Reduced expression of Nkx2.2 and Mbp in P0
Nkx6.1 mutant spinal cord at the cervical region. Cross-sections of
cervical spinal cord from P0 wild-type (A,C,E) and mutant (B,D,F) pups were
hybridized with Nkx2.2 (A,B), Mbp (C,D) and Plp
(E,F) riboprobes. Arrows indicate the MBP+/PLP+ oligodendrocytes in the
mutants.
