Fig. 4. Induction of multinucleation and micronucleation by ionizing radiation.

Fig. 4

Nuclear morphology was quantified through high-content imaging in MCA205 (a–d), 71-7 (e–h), MUCC (i–l) cells, 48 h after irradiation. Cells were stained with Hoechst and propidium iodide after permeabilization to allow segmentation of the nucleus and cytoplasm, respectively. Nuclear area was measured in MCA205 (a), 71-7 (e), and MUCC (i). The roundness of the nucleus was also assessed after irradiation in MCA205 (b), 71-7 (f), and MUCC (j). Percentage of cells with micronuclei is shown for MCA205 (c), 71-7 (g), and MUCC (k) cells. The area of the cells was also measured following irradiation in MCA205 (d), 71-7 (h), and MUCC (l) cells. m Representative picture of micronuclei segmentation. n Representative picture of segmentation mask for the assessment of the nuclear shape.
