In vitro cell migration (wound healing) assay
In vitro scratch assay is an easy, fast and well-developed method to measure normal cell migration and tumor cell invasion. It resembles the functional confirmation for (endothelial-Mesenchymal Transition) EMT gene family switch-on.
Upon creation of an artificial gap, so called ‘‘scratch’’, on a confluent cell monolayer, the cells on both edges move in order to fill-in the gap ‘‘scratch’. The ability of normal / cancer cell to close the wound is proportional to the migration / invasion of cells.
Working protocol includes
· Creating a ‘‘scratch’’ in a cell monolayer.
· Capturing the images at the beginning and at regular intervals during cell migration to close the scratch.
· Comparing the images to quantify the migration rate of the cells.
