  1. U937 myelomonocytic cells were treated for 1 hour with 3 μg/mL docetaxel, after which the drug was washed out and cells were further cultured. Data are the average of 2 experiments, with nearly identical results. For details, see the Methods section.
  2. JC-1 = cells undergoing Δψm transition; E = early apoptosis, i.e. MAA+/PI- or AnnV+/PI-; L = late apoptosis, i.e. MAA+/PI+ or AnnV+/PI+; N = necrosis, i.e. MAA-/PI+ or AnnV-/PI+
