Extract

Fibroblast growth factor (FGF) is a polypeptide found in two forms: basic and acidic. The basic form is produced by many more types of cells than the acidic form, although both bind to the same receptor. These proteins act on a variety of mesodermally and ectodermally derived cells, including chondrocytes, glial cells, myoblasts, endothelial cells, cornea and lens epithelia, adrenal cortical cells, ovarian granulosa cells, periosteal fibroblasts, and osteoblasts. Basic FGF was chosen for the present study for a variety of reasons. First, it has significant cross-species homology, with 98.7% correlation between human and both bovine and avian FGF. Less conservation has been observed in the acidic form. In addition, the basic form has been shown to be 30- to 100-fold more potent, depending on the target tissue.
