| Outline of Final Research Achievements |
In this research, we constructed three-dimensional (3D) tissue shape control of neural stem cells (NSCs) tissues by using closed agarose microchambers for in vitro effective differentiation induction of neurons. As a device for controlling the 3D tissue shape, we first prepared the agarose hydrogel microchambers and sheet. By closing the agarose microchambers with an agarose sheet, lane-shaped NSCs tissues were successfully induced differentiation to neurons and glial cells while maintaining their 3D tissue shape. The thin neural tissues in which neurons were uniformly distributed at high density, was successfully fabricated. We also fabricated the neural microfiber from the human iPS-derived neural stem cells and co-cultured with HUVEC. We successfully observed the vascularization of HUVEC in the 3D fibrin gel with human neural tissues. Finally, we observed that neuronal degeneration in 3D neural tissues by the exposure of glutamic acid.
