Immunohistochemical expression of OCT4 and CD44 in major and minor salivary gland neoplasms
Brazilian Oral Research, 2021 The aim of this study was to identify tumor parenchyma cells exhibiting immunohistochemical profile of stem cells by evaluating the immunoreactivity of OCT4 and CD44 in a number of cases of salivary gland neoplasms. The sample consisted of 20 pleomorphic

STEM CELL IN GASTROINTESTINAL STRUCTURE AND NEOPLASTIC DEVELOPMENT [PDF]
Gut, 2004 Stem cells are primitive cells located in a specialised mesenchymal “niche” that lack expression of any definitive markers of lineage commitment and are therefore difficult to define and identify. Stem cells maintain their capacity for limitless self replication throughout the lifetime of their host, and can also divide to produce daughter cells ...

Stem Cells International, 2020 Endothelial progenitor cells (EPCs) and mesenchymal stem/stromal cells (MSCs) are associated with maintaining tissue homeostasis and tissue repair. Both types of cells contribute to tissue regeneration through the secretion of trophic factors (alone or ...

von Hippel-Lindau disease-associated hemangioblastomas are derived from embryologic multipotent cells. [PDF]
PLoS Medicine, 2007 BACKGROUND: To determine the origin of the neoplastic cell in central nervous system (CNS) hemangioblastomas in von Hippel-Lindau disease (VHL) and its role in tumor formation and distribution, we characterized and differentiated neoplastic cells from ...

Cellular interactions in the tumor microenvironment: the role of secretome [PDF]
, 2019 Over the past years, it has become evident that cancer initiation and progression depends on several components of the tumor microenvironment, including inflammatory and immune cells, fibroblasts, endothelial cells, adipocytes, and extracellular matrix ...

Post-translational deregulation of YAP1 is genetically controlled in rat liver cancer and determines the fate and stem-like behavior of the human disease [PDF]
, 2016 Previous studies showed that YAP1 is over-expressed in hepatocellular carcinoma (HCC). Here we observed higher expression of Yap1/Ctgf axis in dysplastic nodules and HCC chemically-induced in F344 rats, genetically susceptible to hepatocarcinogenesis ...

Heterogeneity of Neoplastic Stem Cells: Theoretical, Functional, and Clinical Implications [PDF]
Cancer Research, 2013 Abstract Accumulating evidence suggests that human cancers develop through a step-wise, but nonlinear process of cellular diversification and evolution. Recent mutational analyses indicate that this process is more complex and diverse than anticipated before whole-genome sequencing methods were readily available.
