Abstract:
PURPOSE: To determine whether the delivery of the SV40 large T-antigen is a feasible method for transiently inducing proliferation of corneal endothelial cells, we delivered liposome-protein complex into bovine corneal endothelial cells(BCEC). METHOD: SV40 large T-antigen protein was introduced into BCEC and positive cells were identified by immunohistochemistry. Quiescent BCECs were double-labeled using BrdU as a measure of de novo DNA synthesis and the Ki-67 was detected by standard immunohistochemical methods. RESULT: The treatment of quiescent BCECs with large T antigen caused an increase in BrdU incorporation and Ki-67 expression. It was tested by time-course study. CONCLUSION: This finding suggests that liposome-mediated delivery of transforming proteins could be a method to transiently induce corneal endothelial cell proliferation.
