Figure 2B: Representative transmission electron microscope images of sections prepared from control and 5-FU-treated wtand p53^-/- cells. An isolation of dead cells was performed in treated samples by collecting floating cells prior to fixation and section preparation.

Supplementary Figure S3: Representative transmission electron microscope images of sections prepared from control and 5-FU-treated (36 h) HCT116 p53^-/- cells. An isolation of dead cells was performed in treated samples by collecting floating cells by means of centrifugation prior to fixation and section preparation.
