L-Ethionine as an inducer of differentiation in human promyelocytic leukemia cells (HL-60). 1980

N Mendelsohn, and J Michl, and H S Gilbert, and G Acs, and J K Christman

The methionine analog, L-ethionine, induces morphological and biochemical changes in cultured HL-60 cells which are indicative of myeloid maturation. After 3 to 5 days of growth in the presence of L-ethionine, the majority of cells have enhanced phagocytic ability. The percentage of cells in the culture which bear complement receptors and which can respond to 12-O-tetradecanoylphorbol-13-acetate with respiratory burst activity increases more than 3-fold. Since the cells fail to become adherent and lose nonspecific esterase activity, we conclude that L-ethionine, like dimethyl sulfoxide, induces granulocytic differentiation of HL-60 cells.
