Stimulation of quiescent corneal endothelial cells by direct delivery of the SV40 large T-antigen protein.

Purpose: To determine whether the delivery of the SV40 large T-antigen is a feasible method for transiently inducing proliferation of corneal endothelial cells.

Methods: Liposome-mediated delivery of proteins into bovine corneal endothelial cells (BCEC) was utilized in this study. Initially, beta-galactosidase was used as a marker protein for cell delivery and cells were assayed colorimetrically for beta-galactosidase activity.
