  • Recombinant human FGF-9 (HZ-1329) induces dose-dependent proliferation of the 4MBr-5 (monkey epithelial) cell line. Cell number was quantitatively assessed by PrestoBlue® cell viability reagent. 4MBr-5 cells were treated with increasing concentrations of recombinant FGF-9 for 7 days. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 4-20 ng/mL.

Background

FGF-9 is a 26 kdA, glycosylated protein that is a member of the FGF superfamily. It primarily binds with FGFR3 and plays prominent roles in the regulating embryonic, lung, and skeletal development. It is a key regulator of male sex determination through promoting the proliferation of pre-Sertoli cells. It signals in conjunction with FGF-10 and SHH to drive the development of the lung mesenchymal space. FGF-9 is also a positive regulator of chondrocyte proliferation and osteogenesis during the bone formation process. Overexpression of loss of FGF-9 during skeletal development often results in aberrant bone growth. (PMID: 28395336, 25772309, 16540513, 25435023).
