Cell exclusion barrier

A “cell exclusion barrier” is not a molecular or pharmacological target but rather a physical structure, such as a silicone or polymer block, used in in vitro assays to exclude cells from a defined area on a culture dish. After removal of the barrier, the migration (or invasion) of cells into the newly available area is tracked to study processes like cell motility, wound healing, and factors affecting migration. These barriers are not biological entities, receptors, enzymes, or proteins, and have no direct physiological or pathophysiological roles[1][2]. This entry is likely due to a misinterpretation or erroneous inclusion from experimental methodology or assay setup literature, rather than from molecular pharmacology or therapeutic targeting contexts.
