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...

We present protocols for the 3-dimensional (3D) encapsulation of cells within synthetic hydrogels. The encapsulation procedure is outlined for two commonly used methods of crosslinking (michael-type addition and light-initiated free radical mechanisms), as well as a number of techniques for assessing encapsulated cell behavior.

This video demonstrates a technique for immunostaining cells encapsulated in a 3D hydrogel. The hydrogel culture containing neural progenitor cells is fixed, permeabilized, and treated with a blocking solution to prevent non-specific immunostaining. A primary antibody cocktail is added to bind specific proteins, followed by fluorescently labeled secondary antibodies and a nuclear stain. The sample is then mounted on a slide and observed under a confocal microscope.

An innovative biofabrication technique was developed to engineer three-dimensional constructs that resemble the architectural features, components, and mechanical properties of in vivo tissue. This technique features a newly developed sacrificial material, BSA rubber, which transfers detailed spatial features, reproducing the in vivo architectures of a wide variety of tissues.
FAQs
Its three-dimensional matrix changes the context in which cells or developmental models interact with their surroundings. Because the scaffold supports adhesion, migration, organization, and signaling, researchers can examine how developmental behaviors arise within a hydrated extracellular environment. This makes the method useful for connecting matrix context with morphogenesis and differentiation.
Controlled polymerization determines when the surrounding collagen solution becomes a stable gel. That transition is important because it converts the liquid mixture into a porous scaffold capable of retaining the embedded biological material while still providing space for cellular movement and organization. In developmental experiments, controlling gel formation helps establish a defined three-dimensional setting for observing tissue formation.
Matrix composition and mechanical context can influence how cells organize and how developmental programs unfold within the scaffold. Varying these properties gives investigators a way to test whether changes in the surrounding extracellular environment affect morphogenesis, differentiation, or tissue formation. This is especially valuable when the goal is to separate biological responses from effects caused by the culture context itself.
A basic workflow places cells, tissues, or a developmental model within a collagen solution, allows that solution to surround the material, and then uses controlled polymerization to form the gel. The resulting porous scaffold provides the three-dimensional culture setting. Subsequent observation can focus on adhesion, migration, organization, signaling, morphogenesis, differentiation, or tissue formation.
Collagen hydrogel encapsulation is useful when researchers need a defined three-dimensional setting for organoid culture, tissue engineering, or cell-based assays. In developmental biology, it can support studies of morphogenesis and tissue formation while preserving attention to matrix composition and mechanical context. The same platform also helps model disease, extending its value beyond basic developmental experiments.
Its relevance extends from normal development to disease modeling because the same three-dimensional environment can be used to examine organization, signaling, morphogenesis, differentiation, and tissue formation under defined laboratory conditions. Researchers can therefore investigate developmental processes while also using the platform to represent altered or disease-related tissue behavior.
