Optokinetic response has been widely used to assess the visual functions of larval zebrafish. Nevertheless, the standard protocol for larval fish is not yet readily applicable in adults1-5. Here, we introduce how to measure the OKR of adult zebrafish using a new protocol which is established in our lab.
FAQs
Shear stress is a fluid force that acts on cells, tissues, materials, or device surfaces as fluid moves past them. Researchers vary flow rates to control this exposure and then examine changes in cell behavior, tissue structure, transport, or device function. Relating the response to the applied flow helps identify how fluid forces shape biological and mechanical performance.
Controlled flow rates create defined conditions for comparing how a biological system, engineered material, or device responds to moving fluid. This control helps researchers distinguish flow-related effects from other influences and evaluate performance under conditions intended to represent realistic operation. The resulting comparisons can reveal whether transport, tissue behavior, or device function changes as fluid exposure changes.
A study may assess several response categories rather than relying on a single measurement. Biological readouts can include changes in cell behavior or tissue structure, while engineered-system readouts can include transport and device function. Examining these outcomes together shows whether fluid exposure produces biological, mechanical, or performance-related effects within the tested system.
Researchers first select the biological system, engineered material, or device and establish controlled flow conditions. They then expose the test system to moving fluid at defined flow rates and measure relevant responses, such as cell behavior, tissue structure, transport, or device function. Finally, they interpret the measurements in relation to fluid forces and the intended operating conditions.
Applications include blood-contacting devices, microfluidic systems, engineered tissues, and vascular models. These systems differ in their biological and mechanical features, but each can be evaluated under moving-fluid conditions to determine how flow affects performance. Studying this range allows researchers to connect fluid exposure with device behavior, tissue responses, or transport within engineered biomedical environments.
The measurements provide evidence for how fluid conditions affect a system’s biological or mechanical outcomes. Researchers can use these results to optimize device designs, develop physiological models, and evaluate performance under more realistic conditions. In biomedical engineering, this supports the development of technologies intended to function more effectively and safely when exposed to moving biological fluids.
