HL-60 cells were induced to differentiate by 1,25-dihydroxyvitamin D3, retinoic acid or DMSO. In order to investigate to which extent this maturation mimics the in vivo monocytic or myeloid differentiation, we compared induced HL-60 cells with peripheral blood monocytes and granulocytes by using a panel of mAbs directed against myeloid cell surface antigens. Upon exposure to 1,25-(OH)2D3, HL-60 cells acquired a differentiation phenotype close to that of mature monocytes. The changes in myeloid cell surface antigens induced by retinoic acid or DMSO paralleled the expression pattern of these molecules in normal granulopoiesis, although maturation was not achieved and partially defective.
