Fig 5. Molecular markers of inferior olive development were initially shifted dorsally, but subsequently, were unaltered.

(A) Coronal sections demonstrate that the expression of Ptf1a in the ventral alar plate was expanded dorsally in Bmpr double knockout mutants (B). Nonetheless, the expression of Rph3a was not altered at 14.5 dpc (C, D) or 16.5 dpc (E, F) embryos or in sagittal sections of 16.5 dpc hindbrains (G, H). Scale bar: D (for C, D), 100 μm; G (for E-H), 100 μm.
