The aim of this thesis is to investigate the influence of soft hydrogels on the chromatin plasticity of epithelial PtK2 and cancer cells SW480. On soft hydrogels, the chromatin of PtK2 cells is organized in heterochromatin. The very soft hydrogels direct the cell death by necrosis. On these substrates, the euchromatin maintained by inhibition of HDAC guides the cells into quiescence. These cells transferred on stiff substrate enter in mitosis. A process of metastatic dissemination is developed from cancer cells grown on very soft hydrogels (E20) and stiff surfaces (glass). On the 1st seeding on E20, cells die. The 2nd seeding on E20 shows that cell viability, motility and heterochromatin percentage increase. On the 3rd seeding on E20, survi...
