We describe an approach to detect and capture invasive cell subpopulations in real-time. The experimental design uses Real-Time Cellular Analysis by monitoring changes in the electric impedance of cells. Invasive cancer, immune, endothelial or stromal cells in complex tissues can be captured, and the impact of co-cultures can be assessed.

A rapid and accurate point-of-care test for invasive pulmonary aspergillosis is presented. It takes advantage of lateral-flow technology using a specific monoclonal antibody that binds to an Aspergillus antigen secreted during pulmonary infections. The assay is compatible with serum and brochoalveolar lavage and represents a novel adjunct test for disease diagnosis.

FAQs
The coated porous membrane provides a tissue-like barrier that cells must penetrate before reaching the opposite side. This added matrix context helps separate movement associated with invasive behavior from simple migration across an unobstructed surface. Researchers can therefore examine how readily cells cross a surrounding structural environment under controlled laboratory conditions.
Migration describes cell movement, whereas invasion reflects movement through a surrounding extracellular matrix or tissue barrier. Separating these behaviors improves interpretation of experiments because a highly motile cell is not necessarily highly invasive. This distinction is especially relevant when comparing tumor aggressiveness or assessing whether a treatment affects matrix penetration rather than movement alone.
Fluorescent labeling makes cells easier to identify against the assay background, while microscopy records their location after the experiment. Automated image analysis can then detect and measure labeled cells that have crossed the membrane. Together, these tools support more consistent quantification and help researchers distinguish invasive cells from unrelated signal or visual background.
Interpretation depends on maintaining controlled assay conditions, including the porous membrane and its extracellular matrix coating. The number of cells found on the opposite side reflects both the cells' behavior and the structure of the assay barrier. Consistent imaging and analysis are therefore important when comparing cell populations, treatments, or experimental conditions.
A typical workflow places cells in a chamber separated from the destination surface by a porous membrane coated with an extracellular matrix substitute. After cells are allowed to move under controlled conditions, researchers identify those that reach the opposite side using fluorescence and microscopy. Image analysis then measures the detected population to support comparisons.
In cancer research, the assay helps characterize tumor aggressiveness by measuring how effectively cells penetrate a matrix-like barrier. Researchers can also investigate molecular pathways that regulate invasion and compare responses between experimental conditions. These results provide a laboratory readout for studying processes associated with cancer progression without relying only on observations of cell movement.
Invasive cell detection also supports studies of immune-cell trafficking, development, and tissue repair. In these settings, the same type of controlled barrier assay can reveal how cells move into or through surrounding matrix environments. The resulting measurements help connect cell behavior with broader biological processes that require coordinated movement and tissue remodeling.
