| Outline of Final Research Achievements |
We identified the expression pattern of WFS1 gene in the primate cochlea using a small non-human primate common marmoset (Suzuki N, 2016). In marmosets, unlike rodents, WFS1 was also expressed in the basal cell of stria vascularis, where severe atrophy was reported in the temporal bone of Wolfram syndrome patients. Based on these findings, we generated WFS1 positive cochlear cells from human iPSCs and its function was analyzed.
