Description

Analysis Note

The biological activity is measured by the dose-dependent stimulation of thymidine uptake using BaF3 cells expressing FGF receptors.

Physical form

Lyophilized from a 0.2 μm filtered buffer solution containing a carrier protein.

Biochem/physiol Actions

Fibroblast growth factor-4 (FGF-4) is a 19 kDa protein identified in NIH-3T3 cell assays as a transforming gene from DNA derived from human tumors, including stomach (hst) and colon cancers, Kaposi′s sarcoma, and hepatocellular carcinoma. FGF-4 includes a secretory signal sequence and shares 42% sequence identity with FGF-Basic at the amino acid level. Both FGF-4 and FGF-Basic bind to the same receptors. Mouse and human FGF-4 shares 82% homology with species cross-reactivity. FGF-4 does not appear to be expressed in normal adult tissues, but during embryogenesis, the gene is spatially and temporally regulated. FGF-4 is a mitogen for fibroblasts and endothelial cells and a potent promoter of angiogenesis. It is believed to be critical in embryonic limb development.
