| Outline of Final Research Achievements |
The aim of this project is to characterize the tympanic border cells localized under the basal membrane of organ of Corti through the transcriptome analysis. We already found slow cycling cells, perhaps progenitor cells of the inner ear tissue, in this area. Making clear their maintenance and regulations will give us some hints for the regeneration of cochlear hair cells.
In this research, we performed 2 things; establish the laser microdissection method and otosphere analysis using neonatal mouse cochlea. The former is good to obtain only the target area of tympanic border cells. In the latter, we found one of the candidate genes as the stemness category was existed in the area of tympanic border cells.
