Outline of Final Research Achievements

Conjunctival epithelium is believed to play an important role in barrier formation and stabilization of tears on the ocular surface. However, due to the absence of suitable conjunctival epithelial cultured cells, detailed examination is difficult. In this study, a human conjunctival epithelial cell line capable of controlling the expression of SV40 large T antigen (SV40LT) gene was prepared according to the presence or absence of doxycycline. In addition, three - dimensional culture was carried out in which epithelial cells and parenchymal cells could be co - cultured in three dimensions, and multilayered conjunctival epithelial cells with markers characteristic of conjunctival epithelium could be confirmed. It is considered that it is possible to construct a culture conjunctival model that can maintain the characteristic differentiation potential of conjunctival epithelium in the long term in the future.
