Although multiple interactions of seminiferous tubules and the interstitial testicular tissue are known, correlation of cytokeratin 18 expressing Sertoli cells with interstitial changes has still not yet been reported. Considering this fact, we focused our investigation on changes of the adjacent interstitial tissue. A total sample of 51 testicular biopsies (from infertile patients) showing mix...

AIM To investigate the distribution of cytokeratins 10, 13, 14 and 19 in biopsy specimens taken from acetowhite and non-acetowhite areas of the cervix. METHOD Cervical biopsy specimens were taken from both acetowhite and non-acetowhite areas from 44 patients who presented with abnormal cervical cytology. The specimens were snap frozen in liquid nitrogen and multiple sections taken from each s...

To determine the performance of intraoperative one-step nucleic acid amplification (OSNA) assay in detecting sentinel lymph node metastases compared to postoperative histology taking into account breast cancer molecular classification and to evaluate whether the level of cytokeratin 19 mRNA copy number may be useful in predicting the likelihood of a positive axillary lymph node dissection. OSNA...

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...

The expression of cholesterol sulfate (CS) is known to increase during squamous differentiation of keratinocytes and to activate the epsilon, eta, and zeta forms of protein kinase C as a signal transduction molecule for the subsequent expression of transglutaminase-1 (TG-1) and cytokeratins. To gain further insight into the regulation of cellular differentiation and tumorigenesis by CS, we exam...

A number of human cytokeratins are expressed during the development of stratified epithelia from one-layered polar epithelia and continue to be expressed in several adult epithelial tissues. For studies of the regulation of the synthesis of stratification-related cytokeratins in internal tissues, we have prepared cDNA and genomic clones encoding cytokeratin 4, as a representative of the basic (...

Apoptosis of mesothelial cells has been demonstrated in vitro but not in vivo. To identify apoptotic pleural cells as mesothelial, we used cytokeratin as a marker and found a striking spheroid, aggregated appearance of cytokeratin in apparently apoptotic mesothelial cells. In in vitro studies, we found that the aggregated cytokeratin pattern correlated with apoptosis in primary mesothelial cell...

Previously, we demonstrated unique protein expression patterns in 20-week-Schistosoma mansoni-infected CBA/J mice with moderate splenomegaly syndrome (MSS) or hypersplemomegaly syndrome (HSS). To better understand the development of severe pathology, we compared the two-dimensional differential in-gel electrophoresis (2D-DIGE) proteomic signatures of livers from uninfected mice and mice infecte...

PURPOSE Recently several reverse transcription-PCR techniques have been proven to be useful for the detection of circulating micrometastases. However, this way intact cell clusters that were found in animal experiments of prognostic value could not be detected. In this study, evaluation and modification of a commercial, cytokeratin-based, immunomagnetic cell separation method was performed for ...
