Abstract

Morphological and functional differentiation of hemopoietic cells is accompanied by the expression of lineage-specific protein markers. NADPH-oxidoreductive enzymatic activities in HL 60 and K 562 leukemic cell lines, compared with granulocytes and erythrocytes, show a NADPH-oxidizing and a NADPH-diaphorase activity. The oxidizing activity, absent in erythrocytes, has the same electrophoretic migration in HL 60 cells and granulocytes while it is different in K 562 cells. The diaphorase, absent in HL 60 cells and granulocytes, has the same migration in erythrocytes and K 562 cells, although with a slightly different quantitative expression. K 562 cells induced to differentiation with arabinofuranosylcytosine show the appearance of a band of NADPH-oxidizing activity of granulocytic type, together with the major band found in these cells.
