Effect of G-CSF on the apoptosis induced by Ara-c in HL-60 leukemic cells / 中国病理生理杂志

ABSTRACT

AIM: To investigate the effect of granulocyte colony stimulating factor (G-CSF) on arabinosyl cytosine (Ara-C)-induced apoptosis in HL-60 leukemia cells. METHODS: The proliferation of HL-60 leukemia cell was observed by hemopoietic cell culture. Apoptosis was measured by the morphology of apoptosis cell , the quantitation of DNA fragmentation with the diphenylamine reaction. The change in drug sensitivity was measured by “MTT”. RESULTS: G-CSF could stimulate the proliferation of HL-60 leukemia cell and colonies of cell increased to 76.5?18.0, compared to the control group (46.5?13.5. P
