Recombinant Human FGF1 Protein

FGF1, also known as acidic fibroblast growth factor (aFGF), is a growth factor and signaling protein encoded by the FGF1 gene. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Three alternatively spliced variants encoding different isoforms have been described. FGF1 is multifunctional with many reported effects. For one example, in mice with diet-induced diabetes that is an experimental equivalent of type 2 diabetes in humans, a single injection of the FGF1 protein is enough to restore blood sugar levels to a healthy range for > 2 days.
