Human promyelocytic leukemia cell line HL-60 in tissue culture was treated with various concentrations of 1,25-dihydroxyvitamin D3, (D3) pentoxifylline (Px) or in combinations. Differentiation to normal granulocytes or monocytes was evaluated by nitroblue tetrazolium (NBT) reducing capacity and morphologic criteria. (D3) produced monocytic differentiation, but sub-differentiation inducing doses of (Px) had no effect. In previous studies we found higher doses of (Px) to produce granulocytic differentiation in vitro and in vivo.
