The typical apoptotic morphological features appeared in MUTZ-1 cells treated with 4mmol/L VPA for 72hours. Pyknosis of cells and nuclei, disintegration of nuclear chromatin and apoptotic body could be observed by light microscopy. Aggregation and margination of nuclear chromatin, concentration of plasm, increment of density and chromatin mass of irregular size could be observed by transmission electronmicroscope. The flow cytometric analysis indicated that the VPA could induce cell apoptosis, apoptosis rate increased in dose-dependent manner, ratio of cells at G0/G1 phase increased and ratio of cells at S phase decreased in dose-dependent manner, the cells were arrested at G0/G1 phase.
