The present study is to culture otocyst cells in fetal, cochlear sensory epithelial cells of neonatal and mature respectively in vitro with refinement of culture media and techniques. Immunocytochemistry and Bromodeoxyuridine labeling are used to detect properties and mitotic status of cultured cells. With the observations about proliferation and differentiation in cultured cells, we want to find the origin of regenerative cells and to understand how these progenitors proliferate and differentiate.
