PDMS microchannels for cell migration assays

Background-hightech-SC.jpg

Study how cells migrate, deform and respond to physical confinement using microchannels with defined geometries. SmartChannel® by 4Dcell provides PDMS-based microchannel devices for investigating cell migration, nuclear deformation and cell behavior in confined environments. Available as ready-to-use glass-bottom dishes or microfabrication kits, SmartChannel supports live-cell imaging and customizable experimental designs.

HOW SMARTCHANNEL WORKS

SmartChannel® technology uses precisely defined PDMS microchannels bonded to a glass substrate to create controlled physical environments for studying cell migration and behavior.

​

Different channel widths, heights and constriction geometries allow researchers to investigate how physical confinement influences cell motility, cellular and nuclear deformation, and the ability of cells to migrate through narrow spaces.

​

The glass-bottom design enables direct observation using live-cell microscopy, supporting the analysis of migration dynamics and cell responses to mechanical constraints.

APPLICATIONS OF MICROCHANNEL-BASED CELL MIGRATION ASSAYS

Immune cell migration

Investigate how immune cells navigate confined environments, including narrow passages that require cellular and nuclear deformation.

Microchannel assays can support the analysis of migration speed, directionality and the ability of cells to traverse physical constrictions.

Cancer cell migration and invasion

Examine how cancer cells migrate through geometrically defined spaces and adapt to physical constraints.

Microchannels provide a controlled setting for investigating cell motility, nuclear deformation and migration behavior relevant to cancer invasion research.

Cell mechanics and nuclear deformability

Explore how physical confinement affects cell shape, nuclear morphology and migration dynamics.

Microchannels with different dimensions and constriction profiles allow researchers to investigate the mechanical adaptations required for cells to move through restricted environments.
