| Outline of Final Research Achievements |
It is reported that S-1, which is administered to about a hundred thousand people a year in Japan, is capable of inducing refractory canalicular obstraction. At present, a specific surgery, which secure tear flow using glass tube, is performed to cure the refractory canalicular obstruction, but it have many complication and low success rate.
We performed the study about development of lacrimal canalicular regenerative therapy using cultured autologous oral mucosal epithelial cell sheet. The results of this study were as follows: firstly, we produced cultured autologous oral mucosal epithelial cell sheet by aseptically harvesting and cultivating oral mucosal epithelial cell of rabbit. Next, the cell sheet could sutured to the subcutaneous tissue. Finally, an existing stent wasn’t appropriate for the preservation of anastomosis site. We conclude that invention of a new stent is needed in order to establish the regenerative therapy.
