Anterior movement of ventral diencephalic precursors separates the primordial eye field in the neural plate and requires cyclops.

Abstract excerpt

A currently favored hypothesis postulates that a single field of cells in the neural plate forms bilateral retinas. To learn how retinal precursors segregate, we followed individual labeled neural plate cells in zebrafish. In the late gastrula, a single field of odd-paired-like-expressing cells contributed to both retinas, bordered posteriorly by diencephalic precursors expressing mariposa. Median...
