GoldBio growth factors are manufactured for RESEARCH USE ONLY and cannot be sold for human consumption!Recombinant Human Fibroblast Growth Factor 4Heparin Secretory Transforming Protein 1 (HSTF1) Oncogene HSTKaposi Fibroblast Growth Factor (KFGF) Transforming Protein KS3HBGF4FGF4 is a member of the Fibroblast Growth Factor family of proteins and was first identified by its oncogenic activity. It plays an important role in embryonic development, acting as an autocrine or paracrine ligand through the FGFR 1c, 2c, 3c, and 4 receptors to support stem cell self-renewal. It is believed that FGF4, with the combined activity one or more apical ectodermal ridge FGFs (FGF2, FGF4, FGF8, and FGF9) works in a positive feedback loop with SHH to control limb development.Sterile Filtered White lyophilized powder.
