TN inhibits osteosarcoma cell growth. (A and B) Effect of TN on the viability of human osteosarcoma cells (MG63 and U-2OS cells). Cells were treated with various concentrations of TN for 48h and viability was measured by MTT assay. The inhibition rate and IC50 values are presented. The statistical difference *P<0.05 compared to the control group.
