Objective(s):The colorectal cancer stem cells (CSCs) with the CD133+ phenotype are a rare fraction of cancer cells with the ability of self-renewal, unlimited proliferation and resistance to treatment. Quercetin has anticancer effects with the advantage of exhibiting low side effects. Therefore, we evaluated the anticancer effects of quercetin and doxorubicin (Dox) in HT29 cancer cells and its ...

Glioblastoma multiforme (GBM) is one of the most common and aggressive types of brain tumors. In GBM, a subpopulation of CD133-positive cancer initiating cells displays stem cell characteristics. The Polycomb group (PcG) and oncogene BMI1 is part of the Polycomb repressive complex 1 (PRC1) that regulates gene expression by modifying chromatin organization. Here we show that BMI1 is expressed in...

PEG-PLGA nanoparticles (NPs) modified with anti-CD133 and tumor-targeting single-chain antibody fragment (scFV-NPs) for systemic delivery of methioninase (METase) and pemetrexed for gastric carcinoma were successfully formulated. The structure characterization and biological functions of METase-pemetrexed-loaded scFV-PEG-PLGA NPs (scFV-METase/pemetrexed-NPs) in vitro were investigated. Function...

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...

Drug eluting stents successfully reduce restenosis at the cost of delayed reendothelialization. In recent years, a novel concept to enhance reendothelialization using anti-CD34 antibody coated stents which capture circulating progenitor cells (EPCs) has been developed with conflicting clinical results. CD133 is a glycoprotein expressed on circulating hematopoietic and putative endothelial-regen...

Background and aim: Recent studies suggest that CD133 as a cancer stem cell marker play significant roles of promoting invasiveness and metastasis in many solid cancers such as colon cancer, breast cancer, pancreatic cancer and so on. The aim of the present study is to explore the role of CD133 in intrahepatic cholangiocarcinoma (ICC). Patients and methods: The expression of CD133 and MMP-9 was...

Cancer stem cells (CSCs) are considered a subset of the bulk tumor responsible for initiating and maintaining the disease. Several surface cellular markers have been recently used to identify CSCs. Among those is CD133, which is expressed by hematopoietic progenitor cells as well as embryonic stem cells and various cancers. We have recently isolated and cultured CD133 positive [CD133+] cells fr...

This study aimed to explore cell surface biomarkers related to cancer stem cells (CSCs) and their role in the tumorigenesis of colon cancer. Various colon cancer cell lines were screened for CD133 and CD44 expression. CD44(high)/CD133(high) and CD44(low)/CD133(low) cells were separately isolated by Fluorescence-Activated Cell Sorting (FACS). The cell proliferation, colony formation, cell cycle ...

PURPOSE Oral squamous cell carcinoma (OSCC), like many solid tumors, contains a heterogeneous population of cancer cells. Recent data suggest that a rare subpopulation of cancer cells, termed cancer stem cells (CSC), is capable of initiating, maintaining, and expanding the growth of tumor. Identification and characterization of CSC from OSCC facilitates the monitoring, therapy, or prevention of...

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...
