Webvisible stress fibres (figure 1). The forces are obtained from the deflections of the posts and the stress fibres revealed by subsequent application of an actin-staining procedure. It is apparent from the image in figure 1 (and numerous other images) that many of the force vectors are inclined to the axis of the visible fibre bundles. WebStress fibers in non-motile cells run between separate focal adhesions, producing isometric tension due to actomyosin contraction. The stress fiber contraction is maintained through dynamic molecular exchanges between preformed and cytoplasmic components. This isometric contraction has been recognized as being essential for extracellular matrix ...
