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 exp...

AIMS To compare the expression of S100 protein, alpha-smooth muscle actin (alpha-SMA) and keratin 19 in odontogenic myxomas and non-odontogenic myxoid lesions. METHODS Formalin fixed, paraffin wax embedded tissue from seven odontogenic myxomas, three soft tissue myxomas, six hyperplastic myxoid dental follicles, two intramuscular myxomas, 12 cardiac myxomas, and seven normal dental follicles ...

Although several cases of signet-ring cell carcinoma (SRCC) in the colorectum have been reported [1,2], there have been no reports of SRCC in the anus. The case presented here is the first reported case of primary pure SRCC of the anus. A 49-year-old man presented with anal bleeding. Colon endoscopy revealed a polyp in the anus, and polypectomy was performed The polypectomy specimen showed pure...

The current authors previously identified circulating cells expressing carcinoembryonic antigen (CEA) messenger ribonucleic acid (mRNA) in 80% of lung cancer patients bearing distant metastases. The current study prospectively validated the data on a novel cohort and extended the study to other mRNAs expressed by neoplastic cells. CEA, cytokeratin 19 and 20, aldolase A and epithelial glycoprote...

To examine the immunohistochemical alterations associated with the histological dedifferentiation of thyroid carcinomas, we performed staining for HBME-1, high molecular weight cytokeratin (HCK), CK 19, thyroid transcription factor-1 (TTF-1) and E-cadherin (E-CD) on 125 various types of thyroid carcinomas. The HBME-1 staining was strong and diffuse in follicular carcinoma (FC), papillary carcin...

BACKGROUND Epithelial splenic cysts (ESC) are uncommon lesions of the spleen. The etiopathogenesis of these cysts is controversial, even if Burrig's theory is the most accredited. The histological distinction between epidermoid and mesothelial cysts may be difficult, particularly for monostratified epithelium. PATIENTS AND METHODS In the period between January 1986 and February 2004, 11 patie...

Papillary thyroid cancer (PTC) metastases in the lymph nodes (LNs) were detected by real-time polymerase chain reaction (PCR) for TG and cytokeratin 19 (CK19), and the obtained results were compared with histopathology. 107 LNs from 34 PTC patients were divided into four blocks by a special cutting device - 2 for histopathology, while the other 2 were tested by quantitative real-time PCR. Metas...

Connexin-43, a major gap junction protein, and cytokeratin-19, one of the intermediate filament keratins, are known to be markers of well-differentiated epithelium. In this study, we investigated the expression of these markers in the head region, lungs, and abdominal organs of 10 human mid-term fetuses. The expression of connexin-43 was found to be restricted to the dura mater, kidney, and adr...
