Fibroblast growth factors (FGFs) are a 22 member family of proteins known to be involved in angiogenesis, wound healing and embryonic development. As a family, they bind to heparin and signal through four receptor tyrosine kinases called, FGFR1, 2, 3 and 4. Although the mechanism remains unclear, FGF-basic 147 (variant of FGF basic 154), also called FGF-2, is a critical component in keeping embryonic stem cells undifferentiated in cell culture systems.

Figure 2: 1µg in each lane (-) non-reducing conditions and (+) reducing conditions in a 4-20% TRIS-Glycine gel, stained with Coomassie Blue. Human FGF basic has a predicted MW of 16.5 kDa.
Figure 1: Human FGF-basic 147 Bioactivity Data. 3T3 cells were cultured with 0 to 10ng/ml human FGF basic. Cell proliferation was measured after 44 hours and the linear portion of the curve was us used to calculate the ED50. The ED50 for this lot of human FGF basic was 0.042-0.063ng/ml. The typical expected range is less than 1ng/ml.
