| Outline of Final Research Achievements |
We generated primitive retinal tissues from human iPS cells, mouse iPS cells and mouse ES cells. We also generated self-induced retinal ganglion cells (RGCs) with functional axons from human induced pluripotent stem cells. After development of the optic vesicle from the induced stem cell embryoid body in three-dimensional culture, conversion to two-dimensional culture resulted in differentiation of RGCs. Axons extended radially from the margin of the clump. Induced RGCs expressed specific markers by quantitative PCR and immunohistochemistry. The long, prominent axons contained neurofilaments and tau, and manifested anterograde axonal transport and sodium-dependent action potentials. The ability to generate RGCs with functional axons uniformly and at a high rate may contribute to both basic and clinical science, including embryology, neurology, pathognomy, and treatment of various optic nerve diseases that threaten vision
