Collagen is another widely used biomaterial that has found popularity in commercial applications, such as photography. Collagen has more recently been used in tissue engineering applications, by creating hydrogels that provide structure to engineered tissue. This video introduces collagen as a biomaterial, demonstrates how it is harvested from porcine skin, and shows how the material is used to create a hydrogel for tissue engineering applications. Finally, several applications of the material...

Source: Amber N. Barron, Ashlea Patterson, and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Hydrogels are a versatile class of cross-linked polymers produced through relatively simple procedures and with generally inexpensive materials. They can be formed from solution and involve a polymer backbone formed from monomer reagents, an initiator which makes the polymer reactive and a crosslinking species which binds the polymer chains...

The biosynthesis of cartilaginous extracellular matrix by chondrocytes can be affected by application of mechanical stimuli. This method describes the technique of applying dynamic compressive strains to chondrocytes encapsulated in 3D constructs and the evaluation of induced changes in chondrocyte metabolism.
FAQs
Crosslinking determines how the hydrogel network behaves. Physical or chemical crosslinking creates the polymer framework, while the type and extent of network formation can be adjusted to influence stiffness, porosity, and degradation. These parameters establish the material conditions surrounding encapsulated cells and help researchers relate matrix design to migration, differentiation, or remodeling outcomes.
Stiffness, porosity, degradation, and biochemical cue presentation provide distinct design variables rather than a single material setting. Adjusting them changes the structural and signaling environment that cells experience inside the gel. Studying these variables together helps bioengineers examine how matrix conditions influence cell behavior and construct systems that more closely represent healthy or diseased microenvironments.
Adhesion and signaling cues give the matrix more than physical support. Their presentation supplies biochemical information alongside the network’s mechanical and structural properties, allowing researchers to investigate cell interactions with a stromal environment. This is particularly useful when the goal is to study differentiation, migration, or tissue remodeling in a setting that includes both material and matrix-derived influences.
Design begins by selecting the structural and biochemical features that the experimental model needs to reproduce. Researchers then tune network properties such as stiffness, porosity, degradation, and cue presentation, incorporate cells or matrix components, and establish the network through physical or chemical crosslinking. The resulting construct provides a controlled platform for observing cell and tissue responses.
These platforms support tissue engineering, organoid culture, and disease modeling because they place cells and matrix components within a tunable three-dimensional environment. In organoid and disease studies, that control helps investigators examine interactions associated with healthy or diseased microenvironments. In regenerative work, the same design principles connect material properties with tissue-building strategies.
Observed changes in cell migration, differentiation, or tissue remodeling can be interpreted alongside the hydrogel’s engineered properties. Because stiffness, porosity, degradation, and biochemical cues are adjustable, researchers can connect a cellular or tissue response to features of the surrounding stromal-like environment. This makes the material useful for linking bioengineered design choices to experimental outcomes and regenerative strategies.
