Combined effects of BMP-4 and IL-6 in OH-2 and ANBL-6 cells.
Cells were incubated with cytokines as indicated for 72 hours. Effects on cellular viability measured by annexin V–FITC and PI flow cytometry in OH-2 cells. Effects on DNA synthesis measured by [3H]-thymidine incorporation in ANBL-6 cells.
