Surface markers are proteins found on the surface of the cell which can be used for its identification. They can play different roles in the cell (e.g. function as either receptors or ligands); they are classified as markers based purely on their specificity for a particular type of cell.

Surface markers are specific proteins found on the surface of the cell which can be used for its identification. They can play different roles in the cell (e.g. function as either receptors or ligands); they are classified as markers exclusively based on their specificity for a particular type of cell.
