Abstract

The quantification of cell-migration behavior in response to gradients is critical for understanding cellular movement and development. The CellASIC® ONIX microfluidic platform offers a microfluidic gradient plate to enable precision-controlled chemoattractant diffusion across perfusion barriers, enabling a quantitatively defined diffusion gradient stable enough for long-term, live cell analysis. Using the system, we studied the effect of a serum gradient on metastatic breast cancer cell migration distance, velocity and degree of chemotaxis.
