Cancer stem cells (CSCs) also known as cancer-initiating cells (CICs) show high tumorigenic activity and high chemo- and radiation resistance. It is, therefore, important to identify CSCs reliably to develop novel curative cancer treatments. In this study, we re-evaluated CSC markers of colorectal cancer for their cellular differentiation and tumorigenic activity, with the aim to identify relia...

Wharton's Jelly- derived Mesenchymal stem cells (WJ-MSCs) have gained interest as an alternative source of stem cells for regenerative medicine because of their potential for self-renewal, differentiation and unique immunomodulatory properties. Although many studies have characterized various WJ-MSCs biologically, the expression profiles of the commonly used stemness markers have not yet been a...

OBJECTIVE Mesenchymal progenitor cells (MPCs) are found in articular cartilage from normal controls and patients with osteoarthritis (OA). Nevertheless, the molecular mechanisms of the proliferation and differentiation of these cells remain unclear. In this study, we aimed to determine the involvement of Wnt/β-catenin signaling in regulating the proliferation and differentiation of MPCs. METH...

We first identified and isolated cellular subpopulations with characteristics of mesenchymal progenitor cells (MPCs) in osteoarthritic cartilage using fluorescence-activated cell sorting (FACS). Cells from osteoarthritic cartilage were enzymatically isolated and analyzed directly or after culture expansion over several passages by FACS using various combinations of surface markers that have bee...

Activated leukocyte cell adhesion molecule (ALCAM/CD166), a member of the immunoglobulin superfamily with five extracellular immunoglobulin-like domains, promotes heterophilic (ALCAM-CD6) and homophilic (ALCAM-ALCAM) cell-cell interactions. Here we describe a fully human single-chain antibody fragment (scFv) directed to ALCAM/CD166. We selected the I/F8 scFv from a phage display library of huma...

Natural compounds such as curcumin have the ability to enhance the therapeutic effectiveness of common chemotherapy agents through cancer stem-like cell (CSC) sensitisation. In the present study, we showed that curcumin enhanced the sensitivity of the double-positive (CD166+/EpCAM+) CSC subpopulation in non-small cell lung cancer (NSCLC) cell lines (A549 and H2170) to cisplatin-induced apoptosi...

Abstract Introduction Activated leukocyte cell adhesion molecule (ALCAM/CD166) is a and one of the potential metastasis ‘soil’ receptors that via homotypic heterotypic interactions, mediates adhesion. The present study investigated clinical, pathological prognostic value ALCAM in patients with pancreatic cancer. Method Pancreatic cancer tissues (n = 223), collected immediately after surgery, we...

In the fall 2013 issue of Caspian Journal of Internal Medicine, an interesting article entitled “The association between CD166 detection rate and clinicopathologic parameters of patients with colorectal cancer” was reported by Shafaei et al. (1). The authors investigated an association between CD166 expression and clinicopathologic characteristics of colorectal cancer. They found an association...

Background: Several factors have been implicated in the pathogenesis of colorectal cancer (CRC) associated with ulcerative colitis (UC). We investigated markers of cancer cell pluripotency, including CD44 and CD166, microRNA-21 (miR-21) and microRNA-215 (miR-215), and APC, K-ras and DCC mutations in biopsy specimens from patients with UC to evaluate any correlations with clinical risk factors. ...
