Recombinant human FGF-basic (146 aa) induces the proliferation of NIH/3T3 cells in a dose-dependent manner. The ED50 for this effect is 0.015 - 0.075 ng/mL. -
Stability Testing for Recombinant Human FGF-basic (146 aa). Recombinant human FGF-basic was aliquoted in pH 7.5, 20 mM Tris, 150 mM NaCl at 0.2 mg/mL. One aliquot was frozen and thawed four times (4x Freeze/Thaw) and compared to the control that was kept at 4°C (Control). The samples were tested for their ability to induce the proliferation of NIH/3T3 cells in a dose-dependent manner. The ED50 for this effect is 0.025 – 0.125 ng/mL.

FGF-basic, also known as FGF-2, is a member of the fibroblast growth factor (FGF) family, which includes 22 members. FGF-acidic and FGF-basic do not have classical secretory signal peptides. The secretion of FGF-2 occurs by direct translocation across the plasma membrane. Multiple forms of FGF-2 derived by alternative translation from AUG and CUG codons from the same mRNA transcript have been described. FGF-2 is expressed in almost all tissues and plays an important role in a variety of normal and pathological processes, including development, wound healing, and neoplastic transformation. FGF-2 is mitogenic for many cell types, both epithelial and mesenchymal. It shows potent angiogenic activity and has been implicated in tumor angiogenesis. FGF-2 significantly promotes the proliferation of adipose-derived mesenchymal cells (AMC) and enhances chondrogenesis in three-dimensional micromass culture. FGF-2 binds to a family of four distinct, high affinity tyrosine kinase receptors, designated FGFR-1 to FGFR-4. In addition, FGF-2 binds to the extracellular matrix (ECM) and heparan sulfate (HS), and is an essential and dynamic regulator of fibroblast growth factor (FGF) signaling. Two fundamentally different crystallographic models have been proposed to explain, at the molecular level, how heparan sulphate enables FGF and FGF receptor (FGFR) to assemble into a functional dimer on the cell surface, although there is controversy regarding the exact manner by which this occurs. FGF-2, αvβ3 integrin, and FGFR-1, form a trimolecular complex required for ERK1/2 activation. MT1-MMP (MMP-14) downregulates the amount of FGF-2 bound to the cell surface, and therefore, it reduces FGF-2 signaling.
