Fibroblast growth factors (FGFs) can stimulate the proliferation of mesenchymal, epithelial and neuroectodermal cells. FGF3 belongs to the heparin binding growth factors family. Members of the family include Acidic FGF (also known as aFGF or FGF 1), basic FGF (bFGF or FGF 2), FGF 3 (also known as Int2) and FGF 4 (also known as hst or Kaposi FGF). FGF 4 was first revealed to be an oncoprotein in Kaposi's sarcoma cells. Other family members include FGF 5, FGF 6, FGF 7 (keratinocyte growth factor, KGF), FGF 8 (AIGF), FGF 9 (GAF) and FGF 10. FGF3 is activated by proviral insertion of mouse mammary tumor virus (MMTV). FGF3 is responsible for most of breast malignancies.
