Cell viability and proliferation. (A) MDA-MB-231 cells cultured with materials for 24 h, stained with fuorescence dyes: calceinAM (green) for live cells and propidium iodide (red) for dead cells. (B) Procedure for nuclei segmentation to count cell number within different materials at different time points (C) MDAMB- 231 cell proliferation obtained by nuclei segmentation after 4 and 7 days of culture for different materials. Symbol *indicates statistical significance (ANOVA test; number of samples: N ≥ 10; p < 0.05).
