(B) Micronucleated cells percentage of CHO-K1 cultures incubated with 21-BD at different concentrations for 24 h. A 24 h incubation with 0.4 mM Methyl methanesulfonate (MMS) was used as a control (A, B, blue circles). (C) Apoptotic and necrotic HeLa cells after 24 h of incubation in control media (white bars), media with 50 µM 21-BD (red bars) or 2 µM digoxin (green bars) for 24 h. Apoptosis and necrosis were detected by flow cytometry ussing an annexin-V translocation assay and the incorporation of propidium iodide in to the nucleus, respectively. <i>P</i><0.01.</p>
