Abstract

Previous studies have demonstrated that mouse embryonal carcinoma (EC) cells produce at least two growth factors: one related to platelet-derived growth factor (PDGF) and another related to basic fibroblast growth factor (FGFb). Since human EC cell lines are being used with increased frequency, the current study examined whether human EC cells produce growth factors, in particular those produced by mouse EC cells. In this study, it was determined that the human EC cell line NT2/D1 produces a heat-labile heparin-binding growth factor that behaves like FGF in a bioassay. Three additional criteria suggest that this factor is closely related or identical to FGFb. The factor from NT2/D1 EC cells, bovine FGFb and FGFb produced by the human hepatoma cell line SK-HEP-1 elute from heparin at similar salt concentrations. The factor produced by NT2/D1 EC cells exhibits a thermal stability curve that is nearly identical to those for bovine FGFb and FGFb from SK-HEP-1 cells. Lastly, NT2/D1 and SK-HEP-1 cells express transcripts of the same size that hybridize with a cDNA probe for human FGFb. In the course of these studies it was determined that NT2/D1 EC cells also express several transcripts that hybridize with a cDNA probe for the human PDGF A-chain. Thus, our findings suggest that the pattern of growth factor production by human and mouse EC cells is evolutionarily conserved.
