| Outline of Final Research Achievements |
Inner ear cell therapy for sensorineural hearing loss has been expected to be an effective therapy for hereditary deafness. We developed a strategy for inner ear cell therapy using bone marrow mesenchymal stem cells (MSC) and established the differentiation method for inner ear like cells from induced pluripotent stem (iPS) cell. For cell therapy targeting hereditary deafness, a more effective cell delivery system to induce the stem cells into cochlear tissue is required. Stem cell homing is one of the crucial mechanisms to be activated for efficient cell delivery to the cochlear tissue. In our study, MCP-1, SDF-1 and their receptors were found to be a key regulator for stem cell recruitment to the cochlear tissue. By activating stem cell homing, we developed a novel strategy to induce a number of stem cells into cochlear tissue.
