Background Recombinant Rat Basic Fibroblast Growth Factor is a potent mitogen and chemoattractant for endothelial cells as well as fibroblasts. Basic fibroblast growth factor (bFGF) is a heparin-binding mitogen for mesoderm-derived cells, also acts as a mitogen, differentiation inducing and maintenance factor for many neuroectodermal cells including glial cells, neurons, paraneurons, and their tumor counterparts. The molecule is expressed in several types of neuroectodermal cells. bFGF occurs in many neuronal target tissues, and can prevent ontogenetic as well as lesion-induced neuron death[1]. In vitro, basic fibroblast growth factor induces an angiogenic phenotype in endothelial cells, which includes chemotaxis, mitogenesis, protease production, beta-integrin expression, and tube formation in three-dimensional gels. It acts by binding to specific tyrosine kinase receptors and to cell-associated heparan sulfate proteoglycans[2]. |
