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...

This video describes the traction force microscopy assay. The assay determines the cellular traction of human colon cancer cells on the extracellular matrix present on soft elastic hydrogel having embedded fluorescent beads. The resultant displacement of fluorescent beads is measured using an appropriate software.
FAQs
Structural proteins within the matrix provide adhesion sites, while associated biochemical cues can affect how cells attach, migrate, organize, and differentiate. These effects arise from interactions between cells and their surrounding matrix rather than from hydration alone. Consequently, changing the matrix composition can alter cellular behavior and help researchers examine how extracellular signals regulate biological function.
Crosslinking converts solubilized matrix material into a stable hydrated network, so the conditions used during this step influence the hydrogel’s resulting structure and mechanical properties. Because cells respond to their physical surroundings, controlled crosslinking is important when researchers want to create a reproducible environment for studying growth, organization, signaling, or tissue-specific behavior.
Researchers can modify the matrix composition and mechanical properties to better represent the tissue under investigation. This adjustment changes the combination of structural support and biochemical cues that cells experience. Tissue-matched formulations are therefore useful for examining how the cellular microenvironment contributes to differentiation, organization, and regeneration in distinct biological settings.
Preparation typically begins with decellularizing tissue to remove cellular material while retaining extracellular matrix components. The remaining matrix is then enzymatically solubilized, producing material that can be handled before crosslinking. Researchers trigger network formation under controlled conditions, allowing the processed matrix to become a hydrated culture environment with defined structural and biochemical characteristics.
This approach is useful when experiments require a cell environment that reflects tissue-derived structural and biochemical features. Reported applications include cell culture, organoid development, tissue engineering, disease modeling, and drug testing. The method can therefore support both basic studies of cell behavior and applied investigations of how cells respond to tissue-relevant surroundings.
ECM hydrogels can help researchers examine how the extracellular environment affects cell adhesion, migration, differentiation, growth, and organization. In biology, this makes them relevant for studying cell signaling and the regulation of tissue function. Their adjustable composition and mechanics also support investigations of regeneration and disease-related changes in the cellular microenvironment.
