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.
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 ...
Porocarcinoma (PCA) (also termed malignant poroma, eccrine porocarcinoma, and malignant eccrine poroma) [1] is a rare form of skin cancer that develops in eccrine sweat glands, i.e. the body's widely distributed major type of sweat glands, as opposed to the apocrine sweat glands which are located primarily in the armpits and perineal area.

- 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).

[7] [2] Negative selection refers to the degradation of thymocytes, and has been found to occur through the help of lysosomes. Lysosomes are present near the nucleus in the cytoplasm of TNCs. [ 7 ] If the internalized thymocytes are selected for negative selection, vacuoles containing the thymocytes move closer to the area with lysosomes and ...
