Adhesion

2019
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...

(2018).This video demonstrates an in vitro gut host–microbe model to study bacterial viability. A co-culture of Caco-2 and HT29-MTX cells is incubated with bacteria pre-treated under simulated digestive conditions. Epithelial barrier integrity is assessed using transepithelial electrical resistance, and fractions from the medium, solubilized...

Intrauterine adhesions (IUAs), the most common pathological consequence of endometrial injury, severely impair reproductive function. Trauma and infection are widely recognized as key risk factors for IUA development. We have successfully established a reproducible rat model of IUAs by combining two critical injury methods: mechanical curettage and infectious induction with lipopolysaccharide.

To study the interaction of bacteria with the blood vessels under shear stress, a flow chamber and an in vivo mesenteric intravital microscopy model are described that allow to dissect the bacterial and host factors contributing to vascular adhesion.
FAQs
These systems limit cell-material interactions through low-adhesion materials, suspension conditions, or surface treatments rather than relying on a conventional attaching surface. The resulting reduction in attachment allows cells to remain viable while organizing in three dimensions. Researchers can therefore examine cell behavior and cellular organization under deliberately controlled cell-environment conditions.
Three-dimensional organization enables aggregates, spheroids, and organoid-like structures to serve as experimental forms rather than treating cells only as isolated surface-attached units. In Non-adhesive Models, these structures support investigations of cell behavior and tissue development, while also providing engineered contexts for studying biomaterials and disease processes.
Unlike systems that depend on attachment to a supporting surface, Non-adhesive Models are designed to make that interaction minimal. This distinction changes the experimental context: observed organization and behavior can be examined without treating substrate attachment as the central condition. The approach is therefore useful when researchers need to control cell-environment interactions.
Model setup begins by selecting a strategy that reduces cell-material interaction, such as a low-adhesion material, a suspension condition, or a surface treatment. The chosen approach must still support cell viability and three-dimensional organization. Researchers can then form aggregates, spheroids, or organoid-like structures suited to the intended engineering investigation.
They are useful when the goal is to study cells or tissues without making attachment to a supporting surface the dominant variable. Engineering researchers apply them to tissue-engineered construct design, evaluation of drug responses, and control of cell-environment interactions. The same platforms also support investigations of biomaterials, tissue development, and disease processes.
Depending on the experimental aim, these models can produce cellular aggregates, spheroids, and organoid-like structures for examining cell behavior, tissue development, biomaterials, or disease processes. They also provide platforms for testing drug responses and informing tissue-engineered construct design. Their value lies in connecting controlled physical conditions with biological organization.
