The mechanics of cancer cell adhesion to its neighboring cells, homotypic or heterotypic, have significant impact on tumor progression and metastasis. Intercellular adhesion has been quantified previously using atomic force microscopy-based methods. Here we show the feasibility of the recently developed fluidic force microscopy (FluidFM) to measure adhesive forces exerted by breast cancer cells. Multiple...
Migration of cancer cells is a key determinant of metastasis, which is correlated with poor prognosis in patients. Evidence shows that cancer cell motility is regulated by stromal cell interactions. To quantify the role of homotypic and heterotypic cell–cell interaction in migration, a two-dimensional migration assay has been developed by microfabrication techniques. Two breast cancer cell lines,...
