Figure 4. MTS proliferation assay in neuroblastoma cell lines exposed to camptothecin (CPT) or topotecan (TPT).
A) MYCN-amplified NB cells; B) MYCN non-amplified NB cells. Error bars indicate standard deviations and statistical significance was verified by Student's T test (*= p<0,05 **=p<0,01 ***=p<0,001 of 48hrs 10v20v250nM vs. CTR; 72h 10v20v250nM vs. CTR )
