(A) Cleaned glass squares (1 cm²) were etched with parallel reference lines and a 1-mm wide silicone strip was placed perpendicular to the reference lines. Cells were seeded on both sides of the silicone. (B) On confluency at 24 hours, the silicone strip was removed, images were captured, and the width of the cell-free zone was analyzed to quantify cell migration.
