The cell-surface proteins of HL-60 human promyelocytic leukemia cells have been compared to those of normal human neutrophils. Proteins of HL-60 cells surface labeled with 125I differed markedly from those of normal neutrophils, as shown by immunoprecipitation and polyacrylamide electrophoresis. Differentiation of HL-60 cells by treatment with dimethylformamide, trans-retinoic acid, or 12-O-tetradecanoylphorbol acetate did not modify the predominant surface-labeled proteins of HL-60 cells to produce a pattern similar to that of normal, mature neutrophils. However, the agents did induce greater quantities of minor cell-surface proteins immunoprecipitated by hyperimmune anti-human neutrophil serum. These immunoprecipitated proteins resembled several of the surface-labeled polypeptides of normal human neutrophils.
