The transmembrane glycoprotein CD133 is a marker commonly used for isolation and analysis of putative cancer stem-like cells. However, analysis of CD133 expression is potentially confounded by the fact that two of the commonly used anti-CD133 antibodies, AC133 and 293C, only recognize CD133 that has undergone glycosylation. Therefore, our aim was to thoroughly examine antibody recognition and m...
Recently, diagnoses of radioiodine-refractory differentiated thyroid cancer (RAI-R DTC) have become more common; prognosis is poor. It has been suggested that cancer stem cells account for radiotherapy resistance. By flow cytometry, different expression percents of CD133 and OCT4 in thyroid cancer cell lines were detected. By real-time quantitative PCR, different mRNA expression of CD133, OCT4,...
BACKGROUND AND AIM CD133 expression in cancer cells has been recognised as a putative cancer stem cell (CSC) marker in epithelial malignancies. CD133 expression was evaluated in gastric cancer and the clinical impact of CD133-positive gastric cancer was clarified. PATIENTS AND METHODS Ninety-seven gastric cancer patients who received curative gastrectomy were enrolled. CD133 expression in can...
Recent efforts in our study of cancer stem cells (CSC) in hepatocellular carcinoma (HCC) have led to the identification of CD133 as a prominent HCC CSC marker. Findings were based on experiments done on cell lines and xenograft tumors where expression of CD133 was detected at levels as high as 65%. Based on the CSC theory, CSCs are believed to represent only a minority number of the tumor mass....
BACKGROUND Cancer stem cell theory suggests that the presence of tumor initiating stem-like cells in cancers may be responsible for cancer progression and relapse. CD133 cell surface maker expression has been used to identify stem-like cells in cancer cell lines. Our goal was to identify such cells in neuroblastoma cell lines and to study the cytotoxicity of common anticancer drugs for those ce...
Synovial sarcoma (SS) is an aggressive tumor that accounts for almost 10% of all soft tissue sarcomas. In this study, we found the expression of CD133 in human SS specimens, thus, we focused on the function of CD133 in SS. Separation of the CD133-positive and -negative subpopulations in SS cell lines clarified that the CD133-negative subpopulation exhibited enhanced growth and hyperphosphorylat...
The success of haematopoietic stem cell (HSC) transplantation largely depends on numbers of transplanted HSCs, which reside in the CD34(+) populations of bone marrow (BM), peripheral blood stem cells (PBSC) and umbilical cord blood (UCB). More specifically HSCs reside in the CD38(low/-) subpopulation, which cannot be objectively discriminated from mature CD34(+) CD38(+) progenitors. Thus, bett...
BACKGROUND Cancer stem cells are thought to play a pivotal role in tumor maintenance, metastasis, tumor therapy resistance and relapse. Hence, the development of methods for non-invasive in vivo detection of cancer stem cells is of great importance. METHODOLOGY/PRINCIPAL FINDINGS Here, we describe successful in vivo detection of CD133/prominin, a cancer stem cell surface marker for a variety ...
Cancer stem cells are an attractive therapeutic target for cancer. The present study examined stem cell characteristics of CD133+ cells isolated from endometrial cancer. Phenotypic characteristics, proliferation, migration, anchorage-independent growth, chemoresistance, gene expression profile and tumorigenicity of CD133+ tumor cells were assessed. Primary tumor exhibited immunoreactivity for C...
We evaluated the healing potential of human fetal aorta-derived CD133(+) progenitor cells and their conditioned medium (CD133(+) CCM) in a new model of ischemic diabetic ulcer. Streptozotocin-induced diabetic mice underwent bilateral limb ischemia and wounding. One wound was covered with collagen containing 2x10(4) CD133(+) or CD133(-) cells or vehicle. The contralateral wound, covered with onl...
