| Research Abstract |
In this study, we report the dynamic, autonomous formation of the optic cup (retinal primordium) structure from a three-dimensional culture of mouse ES cell aggregates. ES cell-derived retinal epithelium spontaneously formed hemispherical epithelial vesicles that become patterned along its proximal-distal axis. While the rigid proximal portion differentiated into pigment epithelium, the flexible distal portion progressively folded inward to form a shape reminiscent of the embryonic optic cup, exhibited interkinetic nuclear migration and generated stratified neural retinal tissue, just as seen in vivo. We demonstrate that optic-cup morphogenesis in this simple cell culture depends on an intrinsic self-organizing program involving stepwise and domain-specific regulations in local epithelial properties.
