BACKGROUND Normal urothelium is characterised by terminally differentiated superficial cells, which express cytokeratin 20 in the cytoplasm. In contrast, cultured human stratified urothelium, which does not undergo complete terminal differentiation of its superficial cells, does not express cytokeratin 20. If spinal cord injury (SCI) affects urothelial differentiation or induces squamous or oth...
Cytokeratins (CK or CKs) are the largest complex group of IF proteins. These are proteins, that are crucial in the development and differentiation of epithelial cells, as well as essential for normal tissue structure and function. The first keratin protein nomenclature was published by Moll et al. (1982) and it has been repeatedly updated in recent years (Schweizer et al., 2006). Based on the r...
Metastatic adenocarcinoma to the liver from an unidentified primary tumor site is a common diagnostic problem. The present study included 41 cases of histologically diagnosed liver biopsies including hepatocellular carcinoma, cholangiocarcinoma and metastatic carcinoma in the liver. All cases were stained immunohistochemically with Cytokeratin 18, 7, and 20, Carbohydrate Antigen 19-9 and Alpha-...
CONTEXT Barrett's esophagus is characterized by the presence of goblet cells. However, when alcian-blue is utilized, another type of cells, called columnar blue cells, is frequently present in the distal esophagus of patients with endoscopic evidence of Barrett's esophagus. Cytokeratin 7 and 20 immunoreactivity has been previously studied in areas of intestinal metaplasia at the esophagogastric...
BACKGROUND Colorectal cancer relapses or metastasizes in 30% of cases. Cytokeratin 20 is present in 95% of colorectal tumors and their metastases and could be used as a marker to detect tumor cells. AIM To assess the usefulness and prognostic value of peripheral blood and bone marrow cytokeratin 20 determinations in patients with colorectal cancer. MATERIAL AND METHODS Blood and bone marrow...
