title: Cultivation of HL-60 cells in a serum-free medium containing granulocyte/macrophage colony-stimulating factor.
abstract: In order to develop a defined cultivation medium for HL-60 cells, we cultivated these cells in a serum-free suspension medium and tested the effect of various growth factors. Of the factors tested, granulocyte/macrophage colony-stimulating factor was most active in growth stimulation. A much lower effect was obtained with granulocyte colony-stimulating factor and transferrin. No effect was found with interleukin-3 and insulin. Granulocyte colony-stimulating factor was the only growth factor tested that also induced differentiation as judged by the nitroblue tetrazolium test. Growth of HL-60 cells in medium containing granulocyte/macrophage colony-stimulating factor (125 U/ml) and transferrin (5 micrograms/ml) as the only protein factors was similar to growth in medium containing 10% serum. No increase in spontaneous differentiation of HL-60 cells in this defined medium was observed. Physiological concentrations of retinol bound to retinol-binding protein and retinyl ester in chylomicron remnants reduced proliferation as well as the level of c-myc oncoprotein and induced differentiation of HL-60 cells cultivated in defined medium. Hence, this defined medium may be useful when studying the function of retinoids in HL-60 cells.
