Abstract:
:Eph tyrosine kinase receptors and their ligands, the ephrins, play a key role in the establishment of retinotectal topography during development. Tectal up-regulation of ephrin-A2 in goldfish, coincident with the reestablishment of a retinotectal map, suggests a similar role during optic nerve regeneration. Here we report a complementary study of EphA3, EphA5 and ephrin-A2 expression in the retina. EphA3 and EphA5 are transiently up-regulated as ascending naso-temporal gradients, whereas ephrin-A2 remains uniform. The expression profiles differ from those in developing chick and mouse, suggesting that different combinations of retinal Eph receptors and ligands can generate topographic guidance information.
