The Mechanical Properties of Breast Cancer Cells and Their Surrounding Microenvironment.

Breast cancer is a major health concern for women worldwide, and therefore, understanding various changes acquired by breast cancer cells is relevant to a better comprehension of the disease. One such change includes alterations to the mechanical properties of breast cancer cells. For example, cells with high malignant potential show lower adhesion forces and higher cell deformability. Mechanical forces, including tensile and compressive forces of the cytoskeleton and the extracellular matrix such as integrin, collagen, and the basement membrane, can affect BC cells. These forces alter the properties of cancer cells, drive them towards invasiveness due to different motility and proliferative profiles, and change their microenvironment. This study will focus on the mechanical characteristics of breast cancer cells and the extracellular matrix. Furthermore, changes induced in breast cancer cells following exposure to mechanical forces will be reviewed. Genes that link phenotype to mechanical forces and the implications of these forces for diagnostics and treatment will be discussed.
