Peritoneal Milky Spots Serve as a Hypoxic Niche and Favor Gastric Cancer Stem/Progenitor Cell Peritoneal Dissemination through Hypoxia-Inducible Factor 1α The authors investigated whether hypoxic peritoneal milky spots were an ideal cancer stem cell niche suitable for gastric cancer stem/progenitor cells (GCSPCs) engraftment. They also evaluated the mechanisms through which the hypoxia-inducible factor-1α-mediated hypoxic microenvironment regulated GCSPC fate. [Stem Cells] Full Article SMURF1 Silencing Diminishes a CD44-High Cancer Stem Cell-Like Population in Head and Neck Squamous Cell Carcinoma Two cancer stem cells-like populations, CD44high/BMI1high and CD44high/ALDHhigh, were enriched from head and neck squamous cell carcinoma cell lines and evaluated for the expression of SMURF1 by qRT-PCR, flow cytometry, and immunoblotting. [Mol Cancer] Abstract | Full Article Anchorage-Dependent Multicellular Aggregate Formation Induces CD44 High Cancer Stem Cell-Like ATL Cells in an NF-κB- and Vimentin-Dependent Manner Investigators demonstrate that adult T-cell leukemia/lymphoma (ATL) cells cultured on a layer of epithelial-like feeder cells form anchorage-dependent multicellular aggregates (MCAs) and that a fraction of MCA-forming ATL cells acquire CD44 high cancer stem cell-like phenotypes. [Cancer Lett] Abstract Cell-Surface Vimentin (csVim): A Mislocalized Protein for Isolating csVimentin+ CD133– Novel Stem-Like Hepatocellular Carcinoma Cells Expressing EMT Markers Scientists examined the potential of targeting csVim to isolate stem-like cancer cells with epithelial-mesenchymal transition (EMT) phenotype, by using a specific csVim-binding antibody, 84-1. Using this antibody, they purified the csVim positive, CD133-negative cell population from primary liver tumor cell suspensions and characterized for stem cell properties. [Int J Cancer] Abstract Tenascin-C: A Novel Candidate Marker for Cancer Stem Cells in Glioblastoma Identified by Tissue Microarrays Tenascin-C (TNC) protein has been identified as a potential marker for cancer stem cells (CSCs) in gliomas based on previous work. Scientists investigated the expression of TNC in tissue microarrays including 17 glioblastoma multiforme, 18 WHO grade III astrocytomas, 15 WHO grade II astrocytomas, four WHO gradeastrocytomas and seven normal brain tissue samples by immunohistochemical staining. [J Proteome Res] Abstract Detection of Circulating Tumor Cell Subpopulations in Patients with Head and Neck Squamous Cell Carcinoma (HNSCC) Investigators assessed which non-hematopoietic cell types are identifiable and whether their numbers differ in pre- and postoperative blood samples. They observed cells showing stem cell-like features like CD133+/CK−/CD45− and cells with both epithelial and stem cell-like features such as CD133+/CK+/CD45−. [PLoS One] Full Article (-)-Epigallocatechin-3-Gallate Inhibits Nasopharyngeal Cancer Stem Cell Self-Renewal and Migration and Reverses the Epithelial-Mesenchymal Transition via NF-κB p65 Inactivation Scientists investigated the self-renewal and migration inhibitory effects of epigallocatechin-3-gallate toward nasopharyngeal cancer stem cells and clarified its mechanism of activity. [Tumor Biol] Abstract Experimental Research of Host Macrophage Canceration Induced by Glioma Stem Progenitor Cells Human glioma stem/progenitor cells transfected with red fluorescent protein gene (SU3-RFP) were seeded inside the abdominal cavity of transgenic nude mice, of which all nucleated cells could express green fluorescent protein (GFP), forming a tumor model with a double‑color RFP/GFP fluorescent tracer.
