Figure 3From: Polysaccharopeptides derived from Coriolus versicolor potentiate the S-phase specific cytotoxicity of Camptothecin (CPT) on human leukemia HL-60 cellsEffect of PSP on [3H] thymidine uptake by HL-60 cells. Cells were pulsed with [3H] thymidine (0.5 Ci/well) for six hours after treatment with or without PSP. Cells were harvested and counted at 24 hour intervals. Values are expressed as mean (SD) (n = 4). * P < 0.001, vs. control.Back to article page
