Abstract：
:During eye formation, inductive phenomena occurring between retinal pigmented epithelium (RPE) and retina are not well understood. After briefly summarizing the normal development of retina and RPE, we present three-dimensional in vitro models of the chick embryonic retina which allows elucidation of RPE-retina interactions. In such retinospheroids, a complete arrangement of layers is achieved, provided that dispersed retinal cells are: (1) young enough; and (2) reaggregated on a monolayer of RPE. Thereby, the RPE extends cell proliferation, while differentiation is much delayed. These findings assign to the RPE a decisive role for the genesis and regeneration of a vertebrate retina.
