Platelet-derived growth factors and fibroblast growth factors are mitogens for rat Schwann cells

Rat sciatic nerve Schwann cells in culture respond to a limited range of mitogens, including glial growth factor, transforming growth factors beta-1 and beta-2 (TGF-beta 1, TGF-beta 2), some cell membrane-associated factors, and to agents such as cholera toxin and forskolin which raise intracellular levels of cAMP. These responses require the presence of FCS, which exhibits little or no mitogen...

Transforming growth factors-beta 1 and beta 2 are mitogens for rat Schwann cells

Transforming growth factor-beta 1 (TGF-beta 1) and TGF-beta 2 were found to be potent mitogens for purified rat Schwann cells, each stimulating DNA synthesis in quiescent cells and also increasing their proliferation rate. Half-maximal stimulation of DNA synthesis occurred at approximately 0.1 ng/ml TGF-beta 1 or TGF-beta 2. Mitogenic stimulation by TGF-beta 1 and TGF-beta 2 was enhanced by for...

Fibroblast growth factors

What are they? Fibroblast growth factors (FGFs) are a family of small (20–30 kDa) intercellular signalling proteins which are frequently found to be glycosylated. The first draft of the human genome identified 29 potential FGF genes, and so far transcripts have been identified for 23 of them. Two FGFs have been identified in Caenorhabditis elegans (Let-756 and Egl-17) while Drosophila appears o...

Human Platelet - Derived Mitogens . I . Identification of Insulinlike Growth

Human platelet lysates contained potent mitogenic activities for MCF-7 human breast-cancer cells in serum-freedefined media. Because these activities were not replaced by known platelet mitogens. such as platelet-derived growth factor or transforming growth factor , we sought to identify the breast cancer cell mitogens by purification and N amino-acid sequencing. Acetic acid extracts of outdate...
