Abstract
Cell migration is a key component in both physiological and pathological events. Normal cell migration is required for essential functions such as development and mounting an immune response. When a defect or alteration occurs with the cell migration process, it can have detrimental outcomes (i.e., cancer metastasis, wound healing, and scar formation). Due to the importance of cell migration, it is necessary to have access to a cell migration assay that is affordable, adaptable, and repeatable. Utilizing the common scratch migration assay, we have developed a new approach to analyzing cell migration that uses general laboratory equipment. The method described uses visual markers that allow for recapturing specific areas of interest without the use of time-lapse microscopy. In addition, it provides flexibility in the experimental design, ranging from altering the migration matrix substrate to the addition of pharmacological modifiers. Furthermore, this protocol outlines a way to account for the area of cell migration, which is not considered by several methods when examining cell migration. This new approach offers a scratch migration assay to a larger audience and will provide greater opportunity for researchers to examine the physiological and pathophysiological impact of cell migration.
