Percentage of apoptotic IL-3Rα^dim and IL-3Rα^bright cells separated from total blast population growing in culture with and without IL-3.

Cells derived from 2 AML patients (patient 100, panel A; patient 112, panel B) were grown in the absence or in the presence of IL-3, and the proportion of apoptotic cells was evaluated by annexin V–FITC binding.
