Comments "...the two- dimensional arrangement of MFs (microfilaments) in contractile fibers, so-called stress fibers, appears to form cable-like structures involved in the maintenance of the cell shape and transduction pathways. F-actin can support large stresses without a great deal of deformation and it ruptures at approximately 3.5N/m^2 [primary source]."
