Background: Human Wharton’s jelly mesenchymal stem cells (HWJMSCs) express liver-specific markers such as albumin, alpha-fetoprotein, cytokeratin-19, cytokeratin-18, and glucose-6-phosphatase. Therefore, they can be considered as a good source for cell replacement therapy for liver diseases. This study aimed to evaluate the effects of various culture systems on the hepatocyte-specific gene expr...
Sjögren's syndrome (SS), an autoimmune exocrinopathy, is associated with dysfunction of the secretory salivary gland epithelium, leading to xerostomia. The etiology of SS disease progression is poorly understood as it is typically not diagnosed until late stage. Since mouse models allow the study of disease progression, we investigated the NOD/ShiLtJ mouse to explore temporal changes to the sal...
6. Stathopoulou A, Vlachonikolis I, Mavroudis D, et al: Molecular detection of cytokeratin-19-positive cells in the peripheral blood of patients with operable breast cancer: Evaluation of their prognostic significance. J Clin Oncol 20:3404-3412, 2002. 7. Zach O, Kasparu H, Wagner H, et al: Prognostic value of tumour cell detection in peripheral blood of breast cancer patients. Acta Med Austriac...
Using a polyclonal antibody against human epidermal keratins and a monoclonal antibody against cytokeratins characteristic of simple epithelia, and the Avidin-Biotin system of immunohistochemistry, we have demonstrated cytokeratin expression in 46% and in 60% of small cell carcinomas of the lung at autopsy respectively. The latter gave a diffuse stronger reaction product than the polyclonal ant...
Background & Aims. Hepatocyte apoptosis may play a role in progression of nonalcoholic fatty liver and oxidative stress seems one of the key mechanisms responsible for liver damage. The aim was to determine the association of oxidative stress with cytokeratin-18 M30 fragment levels, a marker of hepatocyte apoptosis. Methods. Steatosis severity was defined according to Hamaguchi's echographic cr...
Immunohistochemistry (IHC), as such, can be used in routine pathology in order to make correct diagnosis of lung carcinomas. Consequently, more detailed analyses are needed in this field in order to make a wide spectrum of unique combinations for such pulmonary neoplasms. Our aim was to apply an antibody panel, and examine and confirm its utility in the differential diagnosis of lung cancer. Tw...
We studied 14 mucinous and 26 nonmucinous bronchioloalveolar adenocarcinomas (BACs) with thyroid transcription factor (TTF), cytokeratin (CK) 7, CK20, and villin to characterize their staining patterns with these antibodies and identify staining differences between the neoplasms. We also stained 11 mucinous colon adenocarcinomas with the same antibodies to compare their reaction patterns with m...
Cytokeratin polypeptides of human epidermis, of epithelia microdissected from various zones of the pilosebaceous tract (outer root-sheath of hair follicle, sebaceous gland), and of eccrine sweat-glands have been separated by one- and two-dimensional gel electrophoresis and characterized by binding of cytokeratin antibodies and by peptide mapping. The epithelium of the pilosebaceous tract has th...
BACKGROUND To evaluate the expression levels of cyclin D1 in breast papillomas and papillary carcinomas, and to analyze the types of cells that co-express cyclin D1 with cytokeratin 5/6 (CK 5/6) or with cytokeratin 8/18(CK 8/18). METHODS Fifty-nine cases of papillary lesions including 36 papillomas and 23 intracystic papillary carcinomas were examined. Cyclin D1, CK 5/6 and CK 8/18 expression...
