The present study aimed to isolate and identify the properties of the cluster of differentiation (CD)133+ subset in human gallbladder cancer cells. The CD133+ and CD133- subpopulations of the GBC-SD cell line were separated using immunomagnetic separation, and the biological features of the two subpopulations were analyzed in vitro and in vivo. In particular, the present study aimed to determin...

objective: this study was performed to determine the immunophenotype of megakaryocyte progenitor cells differentiated from ucb cd133+ and cd133− cells under the effects of interleukin–3 (il–3), interleukin–6 (il–6), stem cell factor (scf) and thrombopoietin (tpo) in vitro. materials and methods: cd133+and cd133− cells were isolated by using cd133 isolation kit following the manufacturer’s instr...

Atypical teratoid/rhabdoid tumor (AT/RT) is an extremely malignant neoplasm in the central nervous system (CNS) which occurs in infancy and childhood. Recent studies suggested that CD133 could be considered a marker for brain cancer stem-like cells (CSCs). However, the role of CD133 in AT/RT has never been investigated. Herein we report the isolation of CD133-positive cells (CD133(+)), found to...

BACKGROUND AND OBJECTIVE CD133-positive colon cancer stem like cells (CSLCs) are resistant to the conventional cytotoxic drug 5-fluorouracil (5-FU). Wnt signaling pathway plays important roles in colon cancer carcinogenesis and metastasis, and regulates the self-renewal capacity of CSLCs. In the present study, we explored the impact of 5-FU on Wnt signaling pathway of CD133-positive colon CSLCs...

OBJECTIVE CD133 may be the most specific marker of endothelial progenitor cells (EPCs), which are thought to be largely confined to the bone marrow milieu. This study reports on the phenotypic characterization and functional analysis of human CD133+ cells and their generation from cells in the peripheral circulation. METHODS Adult human CD133+ and CD133- cells were isolated from peripheral bl...

CD133 is regarded as a marker of tumor initiating cells in many tumors, including colorectal cancer. O'Brien and Ricci et al. have proved that in primary colorectal tumors there are colorectal tumor stem cells (initiating cells) which are marked by CD133 antigen. Using a genetic knockin lacZ reporter mouse model, Shmelkov et al. challenged this increasingly influential viewpoint and drew two im...

CD133 (prominin-1), a 5-transmembrane glycoprotein, has recently been considered to be an important marker that represents the subset population of cancer stem-like cells. Herein we report the isolation of CD133-positive cells (LC-CD133(+)) and CD133-negative cells (LC-CD133(-)) from tissue samples of ten patients with non-small cell lung cancer (LC) and five LC cell lines. LC-CD133(+) displaye...

BACKGROUND The use of ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles to visualize cells has been applied clinically, showing the potential for monitoring cells in vivo with magnetic resonance imaging (MRI). USPIO conjugated with anti-CD133 antibodies (USPIO-CD133 Ab) that recognize the CD133 molecule, a cancer stem cell marker in a variety of cancers, was studied as a novel and p...
