Impaired terminal differentiation of migrating Cadherin-2 deficient GCs. (A–F) Dorsal views of WT (A, C, E) and pac-/-R cerebella (B, D, F). ISH for the granule cell differentiation markers neuroD (A, B, 3dpf), vglut1 (C, D, 4dpf), and gabαRa6 (E, F, 6dpf). NeuroD expression in pac-/-R cerebella appears scattered, likely resulting from randomly migrating GCs. However, the strength of expression is similar to WT. Vglut1 expression is strongly reduced in pac-/-R and expression of the terminal granule cell differentiation marker gabaRAα6 is almost absent in pac-/-R cerebella (black arrows depict residual patches of expression in ventro-lateral cerebellar regions). cb, cerebellum; ot, optic tectum. |
