Induction of alkaline phosphatase in neutrophilic granulocytes, a marker of cell maturity, from bone marrow of normal individuals by retinoic acid.
We examined whether chemical agents reported to induce differentiation of leukemic cells also have differentiating effects on normal human granulocytes using alkaline phosphatase activity as a marker. Among 11 compounds examined, only vitamin A analogues were shown to induce this activity in granulocytes from bone marrow of normal individuals. Retinoic acid was the most potent inducer of the activity followed by retinal, whereas retinol and retinol acetate did not induce any activity. The effect on the alkaline phosphatase activity by retinoic acid and retinal was considered to reflect their effect on normal granulocytic differentiation and maturation.
