| Outline of Final Research Achievements |
The purpose of this research is to develop a new urethral reconstruction using a small mouth mucosal tissue and cell scaffold material to severe urethral stricture. Broad mouth mucosal tissue is being used as the substitute tissue for an urethral stricture, but the invasiveness to a patient is high and the risk of complications is also increased. In this study, we isolated epithelium cells from a small oral mucosal tissue and tried the identification of the factor which was necessary for the cells viability. As a result, insulin of appropriate concentration was essential to the increase of the human oral mucosal epithelium cells. It was thought that it was necessary to form an epithelium cell layer using the materials which sustained release insulin for the urethral reconstruction.
