dn-Cdk5 rescues inhibition of axonogenesis caused by ca-Rac1. A, Percentage of transfected RGCs with axons exiting the eye in cryostat sections of stage 41 embryos. The numbers of axons that were examined are inparentheses. B, RGC axons coexpressing ca-Rac1 and dn-Cdk5 project dorsally up through the diencephalon (Di) to the optic tectum (Te) in a whole-mount brain. Black dots approximate the tectal borders. Scale bar, 150 μm.
