Inhibition of apoptosis in MARC-2a cells. After incubation for 24 h with 1 μM staurosporine, MARC-145, MARC-2a, and MARC-N cells were stained with FITC-annexin V and PI (a) or Hoechst 33342 (b). The percentage of viable cells was determined by MTT assay (c). The data represent the results of three independent experiments in triplicates, and error bars indicate standard deviations of the means. (*); (**).
