Fig. 2: Stiffness of untreated and daunorubicin-treated cells are presented by Young’s moduli.

The stiffness of individual cells is shown by individual dots (N = 25 for each cell type). The bars and shaded regions are representing mean and standard error of mean (SEM), respectively. a The stiffness of untreated K562 cells was significantly lower (p < 0.005) than the stiffness of treated cells for both concentrations of daunorubicin; and b the stiffness of untreated Jurkat cells was also significantly lower (p < 0.001) than stiffness of treated cells for both concentrations of daunorubicin
