Traction forces of cancer cells
Cell motility of cancer cells is a fundamental problem, and requires precise correlation between cell adhesive and rheological properties. The migration of cancer cells is studied in two dimensions, as cells are seeded onto functionnalized polyacrylamide gels. They migrate by developping focal adhesion sites and modulate their cytoskeleton dynamics by regulating actin and myosin. This research ...
متن کاملQuantifying cellular traction forces in three dimensions.
Cells engage in mechanical force exchange with their extracellular environment through tension generated by the cytoskeleton. A method combining laser scanning confocal microscopy (LSCM) and digital volume correlation (DVC) enables tracking and quantification of cell-mediated deformation of the extracellular matrix in all three spatial dimensions. Time-lapse confocal imaging of migrating 3T3 fi...
متن کاملThe Effect of High Heel Shoes on Tibiofemoral and Patellofemoral joint Contact Forces and Muscle Forces
Introduction: High heel shoes affect the knee joint and can cause arthritis in the tibiofemoral (TFJ) and patellofemoral joints (PFJ). There is a dearth of research investigating the contact forces of TFJ and PFJ. Therefore, the purpose of this study was to assess the effect of high heel shoes on muscle forces as well as TFJ, and PFJ contact forces during walking. Materials & Methods: A tot...
متن کامل3D Traction Forces in Cancer Cell Invasion
Cell invasion through a dense three-dimensional (3D) matrix is believed to depend on the ability of cells to generate traction forces. To quantify the role of cell tractions during invasion in 3D, we present a technique to measure the elastic strain energy stored in the matrix due to traction-induced deformations. The matrix deformations around a cell were measured by tracking the 3D positions ...
متن کاملProbing cell traction forces in confined microenvironments.
Cells migrate in vivo within three-dimensional (3D) extracellular matrices. Cells also migrate through 3D longitudinal channels formed between the connective tissue and the basement membrane of muscle, nerve, and epithelium. Although traction forces have been measured during 2D cell migration, no assay has been developed to probe forces during migration through confined microenvironments. We th...
