Dasatinib does not inhibit proliferation of CLL cells induced by CD154 and IL-4.

<p><b>A:</b> The panels show the assessment of cell division by successive dilution of CFSE at days 6, 9, and 12 of co-culture in the CD154/IL-4 system in one representative experiment. <b>B:</b> The graph shows the mean (±SEM) percentage of cells in each cell division at day 12 from six independent experiments (samples 34, 41, 46, 68, 69 and 70). <b>C:</b> The graph shows the mean (±SEM) cell counts determined for each condition and time point in all six experiments.
