Summary To elucidate possible growth-modulating effects of interleukin 3 (IL-3), granulocyte-macrophagecolony-stimulating factor (GM-CSF) and granulocytecolony-stimulating factor (G-CSF), human transitional cell carcinoma (TCC) cell lines T24, RT112, EJ and 647V were solitarily and continuously exposed to these hematopoietic growth factors at concentrations of 1–100 ng/ml. The murine line MBT-2 was used as a negative and the colon carcinoma cell line HTB38 as a positive control, because of species specificity and known proliferation in response to growth factors, respectively. In the T24 TCC-line solitary and continuous exposure to IL-3, GM-CSF and G-CSF at the highest concentration of 100 ng/ml led to a significant proliferation of cell growth in vitro. Significant proliferation in the RT112 line was only achieved with continuous exposure to IL-3 and GM-CSF (100 ng/ml); G-CSF failed to induce growth modulation in the RT 112 line. No significant proliferative effect of any of cytokines administered was observed in the 647V line. Exposure of the EJ line to cytokines at the highest activity levels had a proliferative effect only in suboptimal growth conditions.
