It is widely understood that mechanical forces in the body can influence cell differentiation and proliferation. Here we present a video protocol demonstrating the use of a custom-built bioreactor for delivering uniaxial cyclic tensile strain to stem cells cultured on flexible micropatterned substrates.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA The importance of materials to human development is clearly captured by the early classifications of world history into periods such as the Stone Age, Iron Age, and the Bronze Age. The introduction of the Siemens and Bessemer processes to produce steels in the mid-1800s is arguably the single most important development in launching the Industrial Revolution that transformed much of Europe and...

Stress-Strain Characteristics of Aluminum

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Aluminum is one of the most abundant materials in our lives, as it is omnipresent in everything from soda cans to airplane components. Its widespread use is relatively recent (1900AD), primarily because aluminum does not occur in its free state, but rather in combination with oxygen and other elements, often in the form of Al2O3. Aluminum was originally obtained from bauxite mineral deposits...

FAQs
These parameters determine the mechanical signal delivered to cells and tissues. Strain magnitude sets the extent of deformation, while loading rate controls how quickly that deformation occurs; duration determines exposure time. Changing any of these variables can alter mechanotransduction and produce different effects on cell alignment, morphology, proliferation, or gene expression.
Directional loading provides a consistent mechanical cue that can guide cellular organization. Under Uniaxial Strain, cells may change their alignment and morphology in relation to the applied axis, helping researchers examine how biological structures adapt to force. This response is particularly relevant when studying tissues whose organization supports directional mechanical loading.
Mechanotransduction converts externally applied mechanical forces into biochemical signals within cells. In a strain experiment, those signals can influence processes such as alignment, morphology, proliferation, and gene expression. Measuring these outcomes helps researchers connect the imposed loading condition with the cellular response, rather than treating deformation as only a physical change.
A controlled study should specify strain magnitude, loading rate, exposure duration, and whether the force is applied continuously or in repeated cycles. These conditions define the mechanical environment experienced by the biological sample. Keeping them consistent supports comparison between experiments and helps identify which loading feature contributes to an observed cellular or tissue response.
Researchers place a biological tissue or engineered construct in a mechanical testing system or cell-stretching device, then select the intended strain magnitude, rate, duration, and loading cycles. After exposure, they examine responses such as cell alignment, morphology, proliferation, or gene expression. This workflow links defined mechanical input to measurable biological outcomes.
The approach is useful when investigators need to evaluate how a biomaterial or engineered construct responds to directional mechanical loading. It can reveal whether the construct supports cellular behaviors associated with mechanically active tissues and can guide tissue-engineering studies by connecting applied strain with changes in organization, growth, and gene expression.
Applying force along one primary axis can represent aspects of the mechanical environment found in tendons, ligaments, and muscle, which experience important directional loads. Researchers use these models to investigate tissue responses, assess engineered constructs, and support development of regenerative therapies. The resulting data provide biological context for evaluating mechanically responsive designs.
