*2.4.2 The transwell migration and invasion assay*

The transwell migration and invasion assay are used to determine the capability of single cells to respond to various chemoattractant(s) including chemokines, growth factors, lipids, or nucleotides. It also contributes to assessing differential cell migration due to the over-expression of a receptor. It also identifies and characterizes the key regulators participating in cell migration [26].
