An 8 kd heparin-binding peptide which stimulates thymidine incorporation in cultures of fetal calf liver erythroid cells was isolated from fetal bovine serum by affinity chromatography on Heparin-Sepharose, ion exchange chromatography, gel filtration and reversed-phase HPLC. The N-terminal sequence of the isolated peptide was identical to the N-terminal sequence of bovine erythrotropin or insulin-like growth factor II (IGF II). The potential heparin-binding site of IGF II is probably situated in the arginine-rich C-peptide region. The affinities of human recombinant IGF I and II were compared with those of apolipoprotein H (a plasma heparin-binding protein) and bovine insulin in a heparin-affinity column. The retention times were in the order: Apolipoprotein H greater than hrIGF II greater than hrIGF I greater than insulin (no retention). This unusual property of IGF II suggests that it may be captured in the extracellular matrix in a similar way to fibroblast growth factor, interleukin 3 or granulocyte/macrophage colony-stimulating factor.
