To clarify the lineage relationship between cells that express the neural stem cell marker nestin and endocrine cells of the pancreas, we analyzed offspring of a cross between mice carrying a nestin promoter/enhancer-driven cre-recombinase (Nestin-cre) and C57BL/6J-Gtrosa26(tm1Sor) mice that carry a loxP-disrupted beta-galactosidase gene (Rosa26). In nestin-cre(+/tg);R26R(loxP/+) embryos, cre-r...

Nestin, an intermediate filament protein and a stem cell marker is expressed in several tumors. Until recently, little was known about the expression levels and the role of Nestin in endometrial cancer. Compared to the immortalized endometrial epithelial cell line EM-E6/E7-TERT, endometrial cancer cell lines express high to moderate levels of Nestin. Furthermore, endometrial tumors and tumor ce...

Introduction: The p19 line of embryonal carcinoma cells develops into neurons, astroglia and fibroblasts after aggregation and exposure to retinoic acid (RA). Dehydroepiandroesteron (DHEA) is a neurosteroid, can increase proliferation of human neural stem cell (NSC) and positively regulated the number of neurons produced. This study was initiated to assess the effect of DHEA on neural progenito...

Nestin, an intermediate filament protein and marker of undifferentiated cells, is expressed in several cancers. Nestin is important for neuronal survival and is a regulator of myogenesis but its function in malignancy is ambiguous. We show that nestin downregulation leads to a redistribution of phosphorylated focal adhesion kinase (pFAK, also known as PTK2) to focal adhesions and alterations in...

The stem cell marker nestin is an intermediate filament protein that plays an important role in cell integrity, migration, and differentiation. Nestin expression occurs in approximately one third of pancreatic ductal adenocarcinoma (PDAC), and its expression strongly correlates with tumor staging and metastasis. Little is known about the mechanisms by which nestin influences PDAC progression. H...

Pupose: Nestin and CD133 are regarded as putative markers of cancer stem cells (CSCs) and related to poor prognosis in various cancer sites. Since few studies have focused on their role in ovarian cancer, we aimed to investigate their predictive value and association with neoangiogenesis. METHODS Immunohistochemical analysis for nestin and CD133 was performed on 85 serous ovarian carcinoma tu...

OBJECTIVES To investigate the association between the expression of nestin, a class VI intermediate filament protein, and pathologic features or survival in patients with urothelial carcinoma of the bladder (UCB). METHODS Nestin expression in tumor cells was immunohistochemically studied in 93 patients with UCB who underwent radical cystectomy with pelvic lymphadenectomy. The associations wit...

PURPOSE This study aimed to investigate the expression and clinical significance of nestin in human astrocytic tumors. METHODS Indirect immunofluorescent staining and flow cytometry were used to quantitatively detect the nestin content in 35 specimens, including 3 normal brain tissues, 29 astrocytic tumor (AT) tissues, and 3 peritumoral tissues. RESULTS In normal brain tissues, nestin expre...

Nestin is an intermediate filament protein (IFP) expressed in undifferentiated cells during CNS development and in CNS tumors. Previous studies have arrived at different conclusions in terms of which types of CNS tumors express nestin. In this report we establish an immunohistochemical protocol using antigen retrieval, which significantly enhances staining with two polyclonal anti-nestin antise...

BACKGROUND Nestin is an intermediary filament protein, expressed in progenitor cells of neural and muscle origin and in activated endothelium. The expression of this protein in tumours can be associated with degree of differentiation, biological potential and/or neoangiogenesis. AIMS The aim of this study was to examine the immunohistochemical expression of nestin in primary non-small cell lu...
