          Abstract

          We investigated the effect of extracellular matrix molecules on the adhesion of retinal pigment epithelial cells and their subsequent proliferation. Fibronectin, collagen type I and vitronectin enhanced their adhesion and proliferation. In addition, the effect of basic fibroblast growth factor (bFGF) on their adhesion and proliferation was studied. bFGF enhanced their adhesion and proliferation, whereas antisense bFGF reduced their adhesion to and their proliferation on extracellular matrix molecules.

          Expression of Fibroblast Growth Factors 1 and 2 in a Human Retinal Pigment Epithelium Cell Line (K1034)

          The primary source of fibroblast growth factors (FGFs) is the retinal pigment epithelium (RPE). Investigations on FGF secretion in RPE primary cultures are hampered by the rapid run-down of cell vitality after a few passages. Therefore, long-term experiments require an alternative to primary cultures. We detected FGF-1 and FGF-2 in the established human K1034 cell line by immunohistochemistry. In addition, mRNA for both FGFs was found by RT-PCR. By immunohistochemistry, the signal was more pronounced with FGF-2 than with FGF-1. K1034 is capable of expressing both FGF-1 and FGF-2. With respect to these features, this cell line can be used as an alternative to primary cultured human RPE cells.
