| abstractText | The mechanisms that establish the dorsal-ventral (D-V) axis of the eye are poorly understood. We isolated two homeobox genes from mouse and chicken, mVax2 and cVax, whose expression during early eye development is restricted to the ventral retina. In chick, ectopic expression of either Vax leads to ventralization of the early retina, as assayed by expression of the transcription factors Pax2 and Tbx5, and the Eph family members EphB2, EphB3, ephrinB1, and ephrinB2, all of which are normally dorsally or ventrally restricted. Moreover, the projections of dorsal but not ventral ganglion cell axons onto the optic tectum showed profound targeting errors following cVax misexpression. mVax2/cVax thus specify positional identity along the D-V axis of the retina and influence retinotectal mapping. |
