The extracellular matrix undergoes substantial remodeling during wound healing, inflammation and tumorigenesis. We present a novel intravital immunofluorescence microscopy approach to visualize the dynamics of fibrillar as well as mesh-like matrix components with high spatial and temporal resolution using epifluorescence or two-photon microscopy.

This manuscript describes a soft lithography-based technique to engineer uniform arrays of three-dimensional (3D) epithelial tissues of defined geometry surrounded by extracellular matrix. This method is amenable to a wide variety of cell types and experimental contexts and allows for high-throughput screening of identical replicates.
FAQs
These matrix components provide complementary functions. Collagen contributes structural support, while elastin supports elastic mechanical behavior. Adhesive glycoproteins help cells attach, and hydrated polysaccharides contribute to the matrix’s water-rich environment. Their combined organization influences how cells interact with surrounding tissue, rather than allowing any single component to determine tissue properties independently.
Cell-surface receptors connect cells to matrix molecules and help translate that contact into biological responses. Through these interactions, cells can regulate attachment, migration, and signaling in response to their surroundings. Consequently, changes in matrix composition or organization may alter cellular behavior even when the cells themselves have not changed.
Matrix remodeling depends on cells continually secreting, modifying, and degrading matrix components. This ongoing turnover allows the surrounding structure to change as tissues develop, maintain their architecture, or respond to damage. Remodeling therefore provides a mechanism for adapting tissue organization over time instead of treating the matrix as a permanently fixed scaffold.
Researchers can compare how differences in matrix composition and stiffness influence cell attachment, migration, mechanical behavior, and signaling. Examining these variables connects physical and molecular matrix properties with cellular responses. Such comparisons are relevant to understanding normal tissue organization as well as changes associated with wound healing, fibrosis, and cancer progression.
Tissue Matrix studies are especially important when researchers need to explain how tissues develop, preserve architecture, or repair damage. They also help investigate pathological changes linked to fibrosis and cancer progression. In biomedical research, this knowledge supports the design of biomaterials intended for tissue engineering by relating matrix properties to cellular and tissue behavior.
Tissue Matrix research can identify how structural composition, hydration, stiffness, and cell-binding interactions affect tissue organization and cellular responses. These insights provide principles for designing biomaterials that better support attachment, migration, signaling, and mechanical behavior. The goal is to relate material characteristics to the biological functions needed for tissue engineering applications.
