BACKGROUND Recent evidences indicate that CD133, a kind of transmembrane protein, can be used as a marker to isolate stem cells from tumors originating from neural crest. This study was undertaken to explore the expression and clinical significance of stem cell marker CD133 in neuroblastoma (NB). METHODS Immunohistochemical staining was used to detect the expression of CD133 in 32 patients wi...
Although CD133 has been proposed as a marker for brain tumor-initiating cells, studies show that a tumorigenic potential exists among CD133(-) glioma cells as well. However, it is not established whether the ability of CD133(-) cells to form tumors is a property confined to a small subpopulation, rather than a common trait associated with most glioma cell types. Thus, we used lentiviral vectors...
The objective of the present study was to determine the 'stemness' characteristics of CD133+ cells (harvested from the squamous cell tongue carcinoma Tca-8113 cell line) in vitro and to observe the tumourigenicity of the CD133+ cells in the bodies of NOD/SCID mice. Single cells from the Tca-8113 cell line were observed for multiplication capacity in vitro. The suspending and pelletizing phenome...
objective: cd133+ umbilical cord blood cells were identified as a hematopoietic stem cell which has the capacity for extensive self-renewal and differentiation. the aim of this study was to identify the effect of staurosporine (sts), a wellknown protein kinase inhibitor on differentiation of cd133+ cells into neural cells. materials and methods: cd133+ cells were enriched by immunomagnetic bead...
In this study, we identified a CD105+CD90.1-CD133-CD55- (CD133-CD55-) population in the fetal skeletal element that can generate bone and bone marrow. Besides osteoblasts and chondrocytes, the CD133-CD55- common progenitors can give rise to marrow reticular stromal cells and perivascular mesenchymal progenitors suggesting they function as the fetal common skeletal progenitor. Suppression of CXC...
BACKGROUND In laryngeal squamous cell carcinoma (SCC), CD133+ cells were found to display cancer stem cell (CSC) characteristics. BMI1 is an oncogene that plays key roles in proliferation in CSCs. However, no published reports have examined the role of BMI1 in laryngeal CSCs. METHODS Immunofluorescence staining confirmed the coexpression of BMI1 and CD133. After sorting, real-time polymerase ...
BACKGROUND The use of stem and/or progenitor cells to achieve potent vasculogenesis in humans has been hindered by low cell numbers, implant capacity, and survival. This study investigated the expansion of CD133+ cells and the use of an injectable collagen-based tissue engineered matrix to support cell delivery and implantation within target ischemic tissue. METHODS AND RESULTS Adult human CD...
Background: Recent studies have suggested that CD44 and/or CD133 expressing pancreatic cancer cells have potential abilities of self-renewal, tumorigenesis and tumor metastasis. The aim of this study was to investigate whether CD44 and CD133 expressions in primary tumor cells correlate to the survival and clinicopathological findings of pancreatic cancer patients. Methods: Pancreatic head carci...
INTRODUCTION Induction of apoptosis in prostatic epithelial cells by doxazosin, terazosin and prazosin has been well documented. However, the biochemical pathways of doxazosin action is still unclear. Aforementioned drugs should lead to decrease of prostate volume, although this effect was never observed in patients suffering from BPH after treatment with α1-antagonists. Probably, it is connect...
Maintenance, repair, and renewal of the epidermis are thought to depend on a pool of dedicated epidermal stem cells (EpiSCs). Like for many somatic tissues, isolation of a nearly pure population of stem cells is a primary goal in cutaneous biology. We used a quantitative transplantation assay, using injection of keratinocytes into subcutis combined with limiting dilution analysis, to assess the...
