Figure 3. Sensitivity of differentiated PC12 cells to four anticancer drugs. Differentiated PC12 cells (day 5) were treated for 48 h without (control)or with the indicated concentrations of docetaxel (A), doxorubicin (B), 5-fluorouracil (5-FU) (C) and gefitinib (D). Cell viability (%) was then determined by the MTT method. Each value represents the mean±S.D. from six determinantions. Significantly different at *p<0.05, **p<0.005 and ***p<0.0005.
