| Outline of Final Research Achievements |
Corneal endothelial cells (CECs) are developed from neural crest cells (NCCs) and may play a role in anterior chamber associated immune deviation, but exact mechanism is yet to be known. In this study, we focused on immunological properties of iPS-cell-derived-NCCs (iPSC-NCCs), because of its high efficiency of induction. iPSC-NCCs were hypoimmunogenic and had immunosuppressive properties in vitro. iPSC-NCCs greatly inhibited T-cell activation (cell proliferation, production of inflammatory cytokines). iPSC-NCCs constitutively expressed TGF-β, and TGF-β produced by iPSC-NCCs played a critical role in T cell suppression. Hypoimmunogenic and immunosuppressive properties of NCCs may contribute to the realization of using stem cell-derived NCCs in cell-based medicine.
