Cell surface adhesions are central in mechanotransduction, as they transmit mechanical tension and initiate the signaling pathways involved in tissue homeostasis and development. Here, we present a protocol for dissecting the biochemical pathways that are activated in response to tension, using ligand-coated magnetic microbeads and force application to adhesion receptors.

Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules. Capillary action is a result of water’s adhesive tendencies. When a narrow glass...

Here, we present a protocol to continuously quantify cell adhesion and de-adhesion processes with high temporal resolution in a non-invasive manner by cell-substrate impedance and live cell imaging analyses. These approaches reveal the dynamics of cell adhesion/de-adhesion processes triggered by matrix modification and their temporal relationship to adhesion-dependent signaling events.
FAQs
Cadherins primarily support cell-to-cell attachment, whereas integrins connect cells with the extracellular matrix or other biological surfaces. Both are membrane proteins, but their binding depends on specific ligands and their intracellular connections. This distinction lets researchers examine whether a change in tissue organization reflects altered neighboring-cell contacts, matrix attachment, or both.
Calcium, mechanical force, and signaling pathways can change how adhesion is established or maintained. Calcium regulates adhesion-related molecular interactions, while force can influence the behavior of membrane protein connections and their cytoskeletal linkages. Signaling pathways add cellular control over these responses, making adhesion dynamic rather than a fixed attachment.
Intracellular adaptor proteins provide the link between adhesion receptors at the membrane and the cytoskeleton inside the cell. That connection helps translate surface binding into an organized cellular response and allows adhesion to be considered alongside cell shape, tissue architecture, and mechanically influenced behavior. Examining this linkage can reveal how attachments affect organization.
A technique-focused workflow can use an adhesion assay to measure interactions, a coated culture substrate to present a defined biological surface, and microscopy to observe resulting cell behavior or organization. Together, these tools let investigators compare attachment under controlled experimental conditions and connect a measured adhesion response with visible changes in cells or tissues.
Cell surface adhesion experiments can examine how cells organize into tissues, migrate across biological surfaces, or participate in wound repair. They also support studies of cancer invasion, where altered attachment may be relevant to tissue behavior. By measuring or manipulating adhesion, investigators can connect surface interactions with broader changes in cellular organization and movement.
Adhesion studies help evaluate how cells interact with biomaterials and engineered tissue environments. Coated culture substrates can provide experimental surfaces for examining these interactions, while adhesion assays and microscopy supply complementary measurements and observations. The resulting information supports efforts to understand or manipulate cell organization when biological structures are designed, maintained, or studied outside their native context.
