Fig. 2From: Evaluation of the anti-cancer potential of Cedrus deodara total lignans by inducing apoptosis of A549 cellsEffects of CTL on the cell cycle of A549 cells. The cells were treated with varying concentrations of CTL (a-e: 0, 10, 20, 30 and 40 μg/mL) for 48 h. The A549 cells were stained with propidium iodide (PI) before FACS Calibur flow cytometry analysisBack to article page
