Survivin expression correlates with the proliferative status of the cells.

Cell-cycle analysis of patient cells at day 0 (A) and after 3 days of culture with CD40L (B) in a CD40L nonresponder (patient 16, Figure 1), in a CD40L responder (patient 3, Figure 1), and in a patient already Survivin⁺ at day 0 (patient 5, Figure 1). PI, propidium iodide.
