Here, we present protocols for analyzing bone remodeling within a lab-on-a-chip platform. A 3D printed mechanical loading device can be paired with the platform to induce osteocyte mechanostransduction by deforming the cellular matrix. The platform can also be used to quantify bone remodeling functional outcomes from osteoclasts and osteoblasts (resorption/formation).

We present a new polyacrylamide hydrogel, called hydroxy-PAAm, that allows a direct binding of ECM proteins with minimal cost or expertise. The combination of hydroxy-PAAm hydrogels with microcontact printing facilitates independent control of many cues of the natural cell microenvironment for studying cellular mechanostransduction.
FAQs
Adhesion complexes and the cytoskeleton act as force-transmitting structures within cells. When tension, compression, shear stress, or changes in substrate stiffness affect the cell, these components help convey mechanical information to signaling systems. Their activity can alter gene expression, migration, growth, and differentiation, linking the cell’s physical environment to longer-term biological behavior.
Mechanosensitive ion channels provide a route through which physical forces can influence electrical signaling inside cells. Mechanical stimulation can activate these channels, connecting changes in the cell’s environment with biochemical or electrical responses. This mechanism is especially relevant to biological systems that detect physical inputs, including touch, hearing, blood-flow conditions, and muscle adaptation.
Substrate stiffness is one mechanical feature that cells can detect through adhesion complexes and the cytoskeleton. Differences in stiffness can modify the signals generated inside a cell, affecting processes such as migration, growth, and differentiation. Consequently, the physical properties of the surrounding material become relevant when analyzing how cells behave in tissues, biomaterials, or engineered environments.
Cells can respond to several distinct mechanical inputs, including tension, compression, shear stress, and substrate stiffness. These forces do not simply describe the environment; they provide information that can be converted into biochemical or electrical signals. The resulting responses may change gene expression and cell behavior, allowing tissues to coordinate activities under varying mechanical conditions.
Mechanotransduction research helps explain how cells and tissues respond during hearing, touch, blood-flow sensing, bone remodeling, and muscle adaptation. These examples connect mechanical inputs with specialized biological functions in different contexts. Studying them can reveal how local forces influence cell behavior and how coordinated responses support tissue activity and adaptation.
The process provides a framework for examining how abnormal or intentionally designed mechanical environments affect cells. Its relevance extends to disease research, biomaterials, and tissue engineering because these fields depend on understanding cellular responses to physical surroundings. Findings can clarify how mechanical conditions influence gene expression, migration, growth, and differentiation in natural or engineered tissues.
Researchers can examine whether mechanical inputs produce biochemical or electrical signals and whether those signals change cellular behavior. Relevant outcomes include altered gene expression, migration, growth, and differentiation. At the tissue level, investigations may also address functions such as blood-flow sensing, bone remodeling, hearing, touch, or muscle adaptation, depending on the biological system under study.
