We present a protocol to synthesize Janus microhydrogels composed entirely of the same base material, poly(N-isopropylacrylamide) (PNIPAAm), with a clearly compartmentalized structure base on the phase separation of a supersaturated NIPAAm monomer solution. The synthesized Janus microhydrogels show unique properties such as anisotropic thermo-responsiveness and organophilic/hydrophilic loading capability.

Listeria monocytogenes is a model organism for studying immune responses and genetic susceptibility to intracellular bacteria in mice. This method enables one to measure bacterial load and generate single-cell suspensions of the liver and spleen from mice for FACS analysis to determine changes in immune cells due to Listeria infection.

Cell-matrix's Response to Mechanical Forces

In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue. Anchoring junctions mechanically attach a cell to the...
FAQs
Researchers track stress and strain to connect an applied force with the resulting change in a material, cell, tissue, or engineered system. Comparing responses under tension, compression, shear, and cyclic loading helps reveal how the tested system behaves under different mechanical conditions, rather than treating every load as equivalent.
Mechanotransduction begins when mechanical cues are converted into biochemical responses by mechanically sensitive molecules and signaling pathways. This link explains why the same external loading environment can produce changes beyond immediate deformation, including cellular or tissue adaptation. In bioengineering, examining this conversion connects measurements of mechanical exposure with biological responses relevant to engineered tissues and devices.
Including cyclic loading in a study allows researchers to examine responses to repeated mechanical exposure, alongside tension, compression, or shear. This is important when the goal is to understand how cells and tissues adapt to their mechanical environment, because a one-time loading condition does not represent every pattern that a biological or engineered system may experience.
A basic assessment applies a defined force mode, such as tension, compression, shear, or cyclic loading, and observes the resulting response. Measurements of stress and strain provide a way to characterize material behavior, while biological systems can additionally be examined for load-triggered signaling or adaptation. The selected loading condition should match the research question.
These measurements show how an implant or scaffold behaves when exposed to relevant mechanical conditions. Researchers can use the resulting characterization to compare engineered materials or structures with the demands of their intended setting. In bioengineering, that information supports development of safer medical devices and scaffolds whose mechanical environment is better aligned with physiological conditions.
Physiological matching helps researchers design medical devices, engineered tissues, and rehabilitation strategies that better reflect the mechanical environments experienced by cells and tissues. This alignment can support safer device development and more relevant studies of adaptation. By considering both loading conditions and resulting biological responses, bioengineers can connect physical design choices with tissue and cellular behavior.
