Figure 1. Cell growth response in retinoblastoma cell lines. The response of cotylenin A (CN-A) on retinoblastoma cell growth was examined using fluorescence cell viability assays repeated in triplicate. Retinoblastoma cells were treated with CN-A at concentrations of 0, 10, or 20 μg/ml and incubated for 0, 3, and 7 days (n=3); the error bar indicates the standard deviation. Asterisks indicate significant differences when compared with the control without CN-A (*p<0.01; **p<0.05).
