Cytokeratins in diagnostic pathology Cytokeratins (CKs) belong to the most fundamental markers of epithelial differentiation CKs comprise a large family of subtypes. Different cell types express different patterns of CK subtypes Cancers generally express CK patterns that at least in part represent the pattern of the putative cell of origin Metastases express CK patterns fairly concordant with those of the primary tumours Cytokeratins a multigene family Highly complex family of polypeptides About 54 distinct human types Class I (type A Acidic): CK9 (64 kda) CK20 (40 kda) Class II (type B Basic/neutral): CK1 (68 kda) CK8 (52.5 kda) Mogens Vyberg, NordiQC 3
