| Outline of Final Research Achievements |
In EMT (epithelial-messenchymal transition) study, retinal pigment epithelial cells have been the main research subject and findings of EMT on retinal pigment epithelial cells have been accumulated. Contrarily, there are few reports, so far, on EMT induced by uPAR through the fibrinolytic system. Therefore, in this study, uPAR was stably introduced into human retinal pigment epithelial cells (ARPE-19), and EMT induced by uPAR was investigated. In consequence, EMT-like changes could not be recognized in ARPE-10 by stably introduced uPAR alone, and collagen gel contraction could not be recognized, either. EMT could not be induced in the retina with a single stimulation of increased expression of uPAR. Involvement of growth factors like TGF-β and cytokines like interleukin should also be considered in the future study.
