Fibroblast growth factor 5, also known as FGF5 is a secreted signaling protein1 that is a member of the fibroblast growth factor gene family.2 FGF5 is widely expressed in embryonic but scarcely in adult tissues.3 FGF5 contributes to the malignant progression of human astrocytic brain tumours by both autocrine and paracrine effects.3 FGF-5 inhibitors are promising substances against hair loss and/or for promoting hair growth.4 FGF5 may also have a functional role in the pathophysiology of age-related macular degeneration (ARMD).5

The biological activity of Human FGF-5 was monitored in a mitogenic assay by measuring the FGF dependent 3H-thymidine incorporation in quiescent NR6R-3T3 fibroblasts (Thomas, K. 1987, Methods in Enzymology 147:120 - 135; Rizzino, A. et al., 1988, Cancer Res. 48:4266). The expected ED50 for this effect is typically 2 - 10 ng/ml in the presence of 1 μg/ml of heparin.
