stress fibers

stress fi·bers

long bundles of microfilaments made up of actin; believed to be involved in the attachment of cultured cells to a substratum and also in the determination of the shape of cells such as fibroblasts; may be involved in cellular mobility.

The pre-load, as Hoyt describes it, is possible because its lamination process allows for a full contour, Uniform Stress Distribution limb design without cutting through critical stress fibers.
After one month of cell expansion, the researchers saw a threefold increase in the size of the cell nucleus and the spreading area, along with an increase in stress fibers.
The cells produce a large number of stress fibers composed of alpha-Smooth Muscle Actin ([alpha]-SMA) in order to increase their retractile properties.
In mammalian cells, Rho proteins Rho/Rac/Cdc42 regulate the formation of the actin cytoskeleton in stress fibers, lamellipodia, and filopodia (1).
This activity leads to an accumulation of stress fibers, which are part of a cell's internal scaffolding.
It is hypothesized that SptP may function in disrupting host actin stress fibers, thereby facilitating membrane ruffling and subsequent bacterial uptake into host cells.
The product stimulates the synthesis of a-smooth muscle actin ([alpha]-SMA) or stress fibers, which generate tension forces that are essential for regulating the mechanical resistance of the dermis and stretching of the skin.
