title: [Combination induction of cell differentiation of HL-60 cells by daidzein (S86019) and BC-4 or Ara-C].
abstract: Experiments demonstrated that the cell differentiation of HL-60 cells induced by low concentrations of daidzein (S86019), BC-4 (active principle of Boswellia carterii Birdw) and Ara-C was not impressive. However, when they were used in combination 80% of HL-60 cells exhibited NBT reduction and 82% of the cells showed phagocytosis after four days exposure to daidzein and BC-4. When HL-60 cells were exposed to daidzein and Ara-c, 70% of the cells exhibited NBT reduction and phagocytosis. Flow cytometry indicated that the majority of the cells were blocked at G1 phase under the induction of combination of daidzein with BC-4 or Ara-C.
