We have found that the gene expression of the ninth member of the fibroblast growth factor (FGF) family, FGF9 was induced during retinoic acid(RA)-induced neuronal differentiation of murine embryonal carcinoma P19 cells. We have reported here the nucleotide sequence of the mouse FGF9 cDNA. The murine cDNA showed 92.4% nucleotide sequence homology to the human FGF9 cDNA and 98.2% homology to that of rats. This mouse FGF9 cDNA encoded a polypeptide consisting of 208 amino acids with amino acid sequence identical to that of rats. Only one amino acid was replaced compared to the human homolog. The highly conserved sequence homology of FGF9 suggests its functional importance. FGF9 was originally isolated from a culture medium of a human glioma cell line as a growth-promoting factor for glial cells [5]. Upon induction of neuronal differentiation by forming cell aggregates with 10(-6) M RA, the gene expression of FGF9 was increased biphasically during the first 96 hours when cells were aggregating and from 168 hours to 192 hours followed by plating onto a tissue culture dish as glia-like cells proliferated. Neither undifferentiated P19 cells nor the cells aggregated without RA remaining undifferentiated expressed FGF9. This indicates that RA regulates the gene expression of FGF9 that may play an important role in neuronal differentiation in both early and late developmental process.
