From: Sulforaphane induces apoptosis and inhibits invasion in U251MG glioblastoma cells
SFN induced apoptosis. U251MG cells treated with 0, 10, 20, 40 µM SFN for 24 h. a The cells were stained with annexin V and PI. The percentages of apoptosis were based on the cells present in the LR and UR quadrants. Total apoptosis percentage, indicating that SFN induced apoptosis in a dose dependent manner. b Statistical analysis of total apoptosis percentage. At 10 µM SFN, no signifiant differences were observed compared with the control group (P > 0.05). At 20 and 40 µM, P < 0.05 versus the control group.
