Abstract：
:The influence of human hepatocyte growth factor (HGF) on the transforming growth factor beta (TGF-beta) bioassay CCL-64 was examined. HGF induced proliferation of the CCL-64 cells and potently counteracted TGF-beta-induced growth inhibition. HGF was not inactivated by transient acidification to pH 2, a commonly used procedure to activate latent TGF-beta. HGF was a stronger mitogen for the mink lung cells than epidermal growth factor (EGF), a known stimulator of CCL-64 cell growth. Costimulation of the cells by these two cytokines resulted in an additive effect on proliferation. In complex biological fluids containing large amounts of HGF, the TGF-beta concentration can be underestimated when determined by the CCL-64 assay. When a fixed amount of TGF-beta is added, the CCL-64 cells can be used as a reliable bioassay for HGF with a sensitivity of about 1 ng/ml.
