Mean percentage (±SD) of cells showing PS externalization and caspase activation in dRib treated PBLs (+) and dRib treated PBLs cultured with Cere, after 1 (T1) and 48 (T48) h of incubation. Microscopy analysis was performed by two independent observers. For quantitative evaluation, mean percentage (±SD) of positive cells was calculated evaluating five fields for each slide
