Objective: To study the effect of meisoindigo on human chronic myelogenous leukemia (CML) cell line K562 cells for exploring the mechanism of meisoindigo in treatment of CML. Methods: Multiple methods, including dose response curve, trypan blue exclusion, cytomorphology, DNA electrophoresis, flow cytometry and TUNEL (TdT mediated dUTP nick and labeling), were used to observe the effect of meisoindigo on K562 cells. Results: Meisoindigo can inhibit the proliferation and induce the apoptosis of K562 cells. Conclusion: The therapeutic mechanism of meisoindigo in treating CML may be related with its proliferation inhibiting and apoptosis inducing effect in CML cells.
