By combining the radial migration assay with injection molded gaskets and a rigid fixture, we have developed a more reliable and sensitive method for measuring radial cell migration. This method is well adapted for use on high throughput automated imaging systems. The use of injection molded gaskets enables low cost replacement of cell-wetted components. Furthermore, the design enables secondary placement of attractants and co-cultures. This device and high-throughput application permit the use of therapeutic screening to evaluate phenotypic responses e.g. cancer cell migration. This approach is orthogonal to other 2D cell migration applications such as scratch wound assays, although here we offer a non-invasive, high-throughput device which is currently not commercially available. Collectively, we have designed a systematic, reliable, high-throughput application to monitor phenotypic responses to chemotherapeutic screens, genetic alterations (e.g. RNAi; CRISPR; others), supplemental regiments, and other approaches offering a reliable methodology to survey unbiased and non-invasive cell migration.
