Keeping the microscope optics clean is important for high-quality imaging. Dust, fingerprints, excess immersion oil, or mounting medium on or in a microscope causes reduction in contrast and resolution. DIC is especially sensitive to contamination and scratches on the lens surfaces. This protocol details the procedure for keeping the microscope clean.

The light microscope is a basic tool for the cell biologist, who should have a thorough understanding of how it works, how it should be aligned for different applications, and how it should be maintained as required to obtain maximum image-forming capacity and resolution. The components of the microscope are described in detail here.

Microscopic Anatomy of Skeletal Muscles

Skeletal muscle cells, also called muscle fibers, are distinctly elongated, multi-nucleated, slender biological units. They are packed with specialized structures designed to facilitate their primary function, which is contraction. The muscle sarcolemma is a plasma membrane enclosing each muscle cell that conducts electrical signals called action potentials. The sarcolemma extends into the cell to form T-tubules, ensuring the neural impulses are uniformly distributed across the entire muscle...

Source: Cayron, J., et al. Multi-scale Analysis of Bacterial Growth Under Stress Treatments. J. Vis. Exp. (2019).This video demonstrates how to prepare and use a microfluidic plate for imaging bacterial cells under stress conditions. It outlines the process of introducing a bacterial culture and a stress-inducing antibiotic medium, followed by cell loading and microscopic setup. Time-lapse imaging in phase-contrast mode is then used to observe the development of elongated, filamentous cells...
FAQs
Controlled vibrations create shear-wave motion within the sample, and motion-sensitive magnetic resonance sequences record how that motion propagates through small-scale structures. Computational analysis then relates the observed wave behavior to local mechanical properties, producing spatial maps rather than a single bulk measurement. This makes regional differences in stiffness and viscoelasticity available for bioengineering analysis.
Measuring both stiffness and viscoelasticity gives a broader mechanical description than reporting stiffness alone. In microscopic MRE, wave travel behavior is analyzed spatially, so the resulting maps can show how mechanical properties vary among small biological structures. That distinction is valuable when structure and mechanics must be considered together in tissue engineering or biomaterial design.
Microscopic MRE can complement conventional imaging and destructive mechanical tests in different ways. Conventional imaging may not resolve the small-scale mechanical variation of interest, while destructive testing can characterize mechanics but may compromise the sample. By mapping properties without relying solely on destruction, the technique supports structure-preserving characterization of engineered tissues and biomaterials.
A practical workflow begins by placing the biological structure, engineered tissue, or biomaterial in a setup where controlled mechanical vibrations can be applied. Motion-sensitive magnetic resonance sequences capture the resulting motion, and computational analysis converts wave behavior into spatial mechanical maps. Researchers can then compare mapped properties with structural features or design goals relevant to the experiment.
The method is suited to questions involving engineered tissues, biomaterials, and cellular-scale structures, because these systems may contain mechanical differences that are difficult to assess through conventional imaging alone. Spatial maps can connect local mechanics with biological structure, helping investigators evaluate how an engineered construct or material may reproduce properties relevant to tissue function.
Mechanical maps provide a way to examine how structure and mechanics relate to tissue function, disease progression, and regenerative design. In bioengineering studies, researchers can characterize an engineered tissue or biomaterial without relying solely on destructive testing. The resulting information adds a mechanical dimension to assessments that might otherwise emphasize structure alone.
