Self-organizing optic-cup morphogenesis in three-dimensional culture

Abstract

Organogenesis relies on the orchestration of many cellular interactions to create the collective cell behaviours that progressively shape developing tissues. Using a three-dimensional embryonic stem cell culture system, this study successfully generated neural retinal tissues that formed a fully stratified neural retinal structure with all the major components located in their proper spatial location as seen during optic-cup development in vivo. This approach might have important implications for stem cell therapy for retinal repair.
