The fibroblast growth factor(FGF) constitude a family of at least seven structurally related polypeptides, among them basic FGF(bFGF) is the most characterized. They play an important role in vivo in embryonic development, angiogenesis,nervous cell system differentiation ,and wound repair. According to the published cDNA sequences. The structural gene of bovine bFGF(bbFGF) was amplified by the PCR method, and constructed in the expression plasmid pVT102U/αˉbbFGF.The expressed product was purified by chromatography on CMˉ52 cellulose and affinity chromatography on heparin Sepharose 4B. The immunogenic property of the expressed product was detected using the ELISA method,and its bioactivity of stimulating effect on 3T3 cells was also mesured.They both showed the same activition with the natural one.
