Cytokeratin 14 (CK14) belongs to the type A (acidic) subfamily of high molecular weight keratins and exists in combination with keratin 5. CK14 has been studied as a prognostic marker in breast cancer. CK14 distinguishes stratified epithelial cells from simple epithelial cells and has been reported useful in the identification of squamous cell carcinomas.
