Endothelial cells line the blood vessel and precursor endothelial cells appear to have a pivotal effect on the organ formation of the heart, the embryonic development of the kidney, and the liver. Several growth factors including the fibroblast growth factors (FGF) seem to be involved in these processes. Ligands such as basic FGF produced and secreted by endothelial cells may also coordinate cellular migration, differentiation, and proliferation under pathological conditions including wound healing, tumorgenesis, and fibrogenesis in the adult. Recently we demonstrated the expression of two secreted FGFs, FGF16, and FGF18, in HUVEC and in rat aortic tissue. In the present report, we confirmed by RT-PCR analysis that FGF18 is wildly expressed in the cardiovascular tissue, while FGF16 showed a more restricted expression pattern. HUVEC clearly demonstrated chemotaxis towards FGF16 and FGF18. Both FGFs also enhanced cell migration in response to mechanical damage. However, recombinant FGF16 and FGF18 failed to induce endothelial cell proliferation or sprouting in a three-dimensional in vitro angiogenesis assay. Fgf18 expression was earlier reported in the liver, and we detected FGF18 expression in liver vascular and liver sinusoidal endothelial cells (LSECs), but not in hepatic parenchymal cells. Recombinant FGF18 stimulated DNA synthesis in primary hepatocytes, suggesting, that endothelial FGF18 might have a paracrine function in promoting growth of the parenchymal tissue. Interestingly, FGF2, which is mitogenic on endothelial cells and hepatocytes stimulates a sustained MAPK activation in both cell types, while FGF18 causes a short transient activation of the MAPK pathway in endothelial cells but a sustained activation in hepatocytes. Therefore, the difference in the time course of MAPK activation by the different FGFs appears to be the cause for the different cellular responses.
