| Outline of Final Research Achievements |
The vocal folds have unique structure, which contains a "Pudding" layer on an intralaryngeal muscle layer. Many researchers had tried to elucidate pathophysiological mechanism in the vocal folds, but wound healing process and anatomical understanding are still unclear. We, therefore, established two new mouse surgery models. The first model is intra-bone bone marrow transplantation model in mice. To track bone marrow derived cells in the vocal folds, bone marrow tissue from transgenic mice with expressing green fluorescent protein was transplanted into femoral bones of wild-type mice. The other is an endoscopic injury model to vocal folds in mice. Since their vocal structures are very tiny, this procedure was very challenging without open cervical surgeries. We established new surgical tools to create vocal fold injuries without any lethal damage. The application of these models and commercially available gene-manipulated mice would enhance the researches in the vocal folds.
