CoCl2, a Mimic of Hypoxia, Induces Formation of Polyploid Giant Cells with Stem Characteristics in Colon Cancer Researchers investigated the generation of polyploid giant cancer cells in colon cancer cells and identified mechanisms of formation. Treatment of HCT-116 and Caco-2 colon cancer cells with the hypoxia mimic cobalt chloride (CoCl2) induced the formation of cells with larger cell and nuclear size, while the cells with normal morphology were selectively eliminated. [PLoS One] Full Article Establishment of Highly Tumorigenic Human Colorectal Cancer Cell Line (CR4) with Properties of Putative Cancer Stem Cells Researchers report the establishment of a novel cancer-initiating cell-enriched, highly tumorigenic and clonogenic colon cancer cell line, CR4, derived from liver metastasis. [PLoS One] Full Article Knockdown of miR-210 Decreases Hypoxic Glioma Stem Cells Stemness and Radioresistance To explore the possibility of miR-210 as an effective therapeutic target to hypoxic glioma stem cells, scientists employed lentiviral-mediated anti-sense miR-210 gene transfer technique to knockdown miR-210 expression and analyze phenotypic changes in hypoxic U87s and SHG44s cells. [Exp Cell Res] Abstract Cancer Stem Cell Phenotype Is Supported by Secretory Phospholipase A2 in Human Lung Cancer Cells Viral knockdown and chemical inhibition of secretory phospholipase A2 group IIa (sPLA2) reduce tumorsphere formation in lung cancer cells demonstrate for the first time that sPLA2 plays an important role in cancer stem cells. [Ann Thorac Surg] Abstract QKI Impairs Self-Renewal and Tumorigenicity of Oral Cancer Cells via Repression of SOX2 Researchers showed that reduced Quaking (QKI) levels were observed in many human oral cancer samples. Moreover further reduction of QKI expression in cancer stem cells (CSCs) was detected compared with non-CSCs in oral cancer cell lines. [Cancer Biol Ther] Full Article Characterization of Side Population Cells Isolated from the Colon Cancer Cell Line SW480 The self-renewal, differentiated progeny, clone formation, proliferation, invasion ability, cell cycle, chemosensitivity and tumorigenic properties in side population (SP) and non-SP cells were investigated through in vitro culture and in vivo serial transplantation. [Int J Oncol] Abstract Resistance of Oral Squamous Cell Carcinoma Cells to Cetuximab Is Associated with EGFR Insensitivity and Enhanced Stem Cell-Like Potency Researchers characterized cetuximab-resistant oral squamous cell carcinoma (OSCC) cell lines. The human OSCC cell lines HSC3, HSC4 and SAS were used. Cetuximab-resistant SAS cells not only engaged in epidermal growth factor receptor (EGFR)-independent growth but also exhibited stem cell-like properties. [Oncol Rep] Abstract Cancer Stem Cell Differentiation: TGFβ1 and Versican May Trigger Molecules for the Organization of Tumor Spheroids Scientists constructed an in vitro differentiation model for cancer stem cells (CSCs). CSCs isolated and proliferated for one passage were maintained as monolayers or spheroid-forming cells with serum included media for differentiation process.
