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.

Cell Adhesion in Plants

Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses. Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose, and...
FAQs
Cell-surface receptors convert contact with a modified substrate into an organized adhesion structure. When receptors bind extracellular matrix proteins or an adhesive polymer, they help assemble focal adhesions, which connect the cell surface to the actin cytoskeleton. This physical organization gives cultured cells a stable substrate relationship, supporting interpretable changes in shape, growth, migration, and differentiation.
The main distinction is the type of surface modification. Collagen and fibronectin are extracellular matrix proteins, whereas poly-L-lysine is a charged polymer. These choices therefore provide different material contexts for cell attachment and spreading. Selecting among them is relevant when an experiment needs to examine how cells respond to matrix-associated or polymer-modified substrates.
Adhesion quality affects more than whether cells remain on a surface. Improved attachment is associated with consistent cell growth and morphology, as well as with migration and differentiation measurements. A surface that supports dependable cell-substrate interactions can therefore reduce variation caused by uneven attachment, making cultured-cell observations easier to compare across experiments.
Common choices include collagen and fibronectin, which represent extracellular matrix components, and poly-L-lysine, a charged polymer. These materials are used to modify culture surfaces before cells are maintained or studied on them. The appropriate choice depends on the biological question, because the resulting substrate provides the setting in which attachment, spreading, morphology, and cell behavior are evaluated.
In microscopy, improved attachment helps maintain attached cells and their morphology for observing cell behavior on a substrate. In tissue engineering, the same principle supports models that examine tissue-like behavior in vitro. More broadly, these methods provide a controlled way to study cell-substrate interactions, including patterns related to growth, migration, differentiation, and spreading.
Researchers should consider this approach when an experiment depends on consistent attachment or reproducible cell-substrate interactions. It is especially relevant for cultures and assays examining morphology, migration, differentiation, or growth. In biological techniques, surface modification also supports microscopy and tissue-engineering models where substrate behavior is part of the research question.
