Keratin, type II cytoskeletal 7 also known as cytokeratin-7 (CK-7) or keratin-7 (K7) or sarcolectin (SCL) is a protein that in humans is encoded by the KRT7 gene. [5] [6] [7] Keratin 7 is a type II keratin. It is specifically expressed in the simple epithelia lining the cavities of the internal organs and in the gland ducts and blood vessels.
Until recently the diagnostic method predominantly depended on identifying antibodies' responses that are positive for adenocarcinoma and negative for mesothelioma. [3] Cytokeratin 5/6 (CK5/6) is a biomarker that has emerged as a valuable tool in distinguishing epithelioid pleural mesothelioma from metastatic adenocarcinoma.
A Toker cell is an epithelial cell with clear cytoplasm in the nipple of some women. [1] Toker cells are believed to develop from sebaceous glands. [1] They are cytokeratin 7 (CK7) positive, in contrast to squamous epithelium. [1] Rarely, they can be numerous and atypical, and difficult to distinguish from malignant cells of Paget's disease of ...

The term cytokeratin began to be used in the late 1970s, when the protein subunits of keratin intermediate filaments inside cells were first being identified and characterized. [2] In 2006 a new systematic nomenclature for mammalian keratins was created, and the proteins previously called cytokeratins are simply called keratins (human ...
- The right panel shows high magnification on a positive area, confirming adenocarcinoma, as it shows tumor cells with large nuclei and prominent nucleoli. AE1/AE3 is an antibody cocktail that is used in immunohistochemistry , being generally positive in the cytoplasm of carcinomas (cancers of epithelial origin).

SGc tumor cells stain positive with epithelial membrane antigen (EMA), cytokeratin -7 (CK-7), Ber-EP4, adipophilin, perilipin, and androgen receptor (AR). [ 6 ] [ 17 ] [ 2 ] Meanwhile, SGc cells are negative for carcinoembryonic antigen (CEA), gross cystic disease fluid protein, and S100 protein, helping differentiate SGc from SCC and BCC.
