简介：
Overview
This study presents a cell-edge protrusion assay to investigate the dynamic parameters of spreading cells, including protrusions, retractions, and ruffles. This method is particularly significant as it correlates with cell migration, aiding in the identification of critical proteins and signaling mechanisms involved in cell motility.
