Evolution of p27 expression in B-CLL cells after 5 days of culture in the presence of IL-4 (10 ng/mL) or fludarabine (5 × 10-6 mol/L). For each patient, results are expressed as the ratio of p27 expression at day 5 of culture in medium + IL-4 or medium + fludarabine to p27 expression at day 5 in medium alone (control value = 100%).
