Iron deprivation of HL-60 cells with deferoxamine B mesylate (DFO) induced apoptosis. DNA fragmentation became apparent with 10(-6) M DFO after 48 h treatment. The apoptosis peak according to the DNA histogram on flow cytometry and typical nuclear collapse and were observed microscopically after 48 h treatment with 10(-4) M DFO. Cells treated with 10(-4) M DFO for as little as 24 h were shown to be committed to apoptosis, as chromatin condensation progressed gradually thereafter.
用甲磺酸去铁胺（DFO）剥夺HL-60细胞的铁会诱导细胞凋亡。在10⁻⁶M DFO处理48小时后，DNA片段化变得明显。在用10⁻⁴M DFO处理48小时后，通过流式细胞仪的DNA直方图观察到凋亡峰以及典型的核固缩，并在显微镜下观察到。用10⁻⁴M DFO处理仅24小时的细胞就显示出会发生凋亡，因为此后染色质凝聚逐渐进展。
