Non-viral gene transfer of growth factor genes in ocular cells

Growth factors as intercellular messangers play a key role in wound healing. So far numerous growth factors have been characterized and their molecular structure has been clarified. The biological effects of some of them take place intracellularly. The availability of growth factors within the cell displays a main problem for specific manipulation of their activity. To target the cell membrane and the intracellular space liposomes have been shown to be very effective. In this project growth factor genes will be transfected into ocular cells, which possess only a limited capacity for proliferation under physiological conditions (corneal endothelium). Modulating the proliferation behavior of these cells via non-viral gene transfer could be helpful in developing new therapeutic approaches with clinical relevance for maintanence of vision.
