    3D Culture Protocol for Testing Gene Knockdown Efficiency and Cell Line Derivation
    Authors:  Jan Strnadel, Sang Myung Woo, Sunkyu Choi, Huawei Wang, Marian Grendar and Ken Fujimura, date: 06/05/2018, view: 863, Q&A: 0
    [Abstract] Traditional 2D cell cultures with cells grown as monolayers on solid surface still represent the standard method in cancer research for drug testing. Cells grown in 2D cultures, however, lack relevant cell-matrix and cell-cell interactions and ignore the true three-dimensional anatomy of solid tumors. Cells cultured in 2D can also undergo ...
    Primary Cultures from Human GH-secreting or Clinically Non-functioning Pituitary Adenomas
    Authors:  Roberto Würth, Alessandra Pattarozzi, Federica Barbieri and Tullio Florio, date: 04/05/2018, view: 830, Q&A: 0
    [Abstract] Pituitary adenomas are among the more frequent intracranial tumors usually treated with both surgical and pharmacological–based on somatostatin and dopamine agonists–approaches. Although mostly benign tumors, the occurrence of invasive behaviors is often detected resulting in poorer prognosis. The use of primary cultures from human pituitary ...
    FACS-based Isolation of Neural and Glioma Stem Cell Populations from Fresh Human Tissues Utilizing EGF Ligand
    Authors:  Jessica Tome-Garcia, Fiona Doetsch and Nadejda M. Tsankova, date: 12/20/2017, view: 2023, Q&A: 0
    [Abstract] Direct isolation of human neural and glioma stem cells from fresh tissues permits their biological study without prior culture and may capture novel aspects of their molecular phenotype in their native state. Recently, we demonstrated the ability to prospectively isolate stem cell populations from fresh human germinal matrix and glioblastoma ...
    Myeloid Progenitor Transformation Assay
    Authors:  Hiroshi Okuda and Akihiko Yokoyama, date: 12/05/2017, view: 1355, Q&A: 0
    [Abstract] Numerous oncogenes have been identified to cause leukemia. For example, chromosomal translocation generates various fusion genes of the mixed-lineage leukemia (MLL) gene and a partner gene in leukemia, whose gene products transform primary myeloid progenitors into an immortalized state. To characterize the transforming ability of leukemic ...
    Isolation and Separation of Epithelial CD34+ Cancer Stem Cells from Tgfbr2-deficient Squamous Cell Carcinoma
    Authors:  Heather A. McCauley and Géraldine Guasch, date: 09/05/2017, view: 2140, Q&A: 0
    [Abstract] Most epithelial tumors have been shown to contain cancer stem cells that are potentially the driving force in tumor progression and metastasis (Kreso and Dick, 2014; Nassar and Blanpain, 2016). To study these cells in depth, cell isolation strategies relying on cell surface markers or fluorescent reporters are essential, and the isolation ...
    Teratoma Formation Assay for Assessing Pluripotency and Tumorigenicity of Pluripotent Stem Cells
    Authors:  Shingo Miyawaki, Yohei Okada, Hideyuki Okano and Kyoko Miura, date: 08/20/2017, view: 3445, Q&A: 0
    [Abstract] Pluripotent stem cells such as induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) form teratomas when transplanted into immunodeficient mice. As teratomas contain all three germ layers (endoderm, mesoderm, ectoderm), teratoma formation assay is widely used as an index of pluripotency (Evans and Kaufman, 1981; Hentze et al. ...
    Tumorigenicity Assay in Nude Mice
    Authors:  Feng Du, Xiaodi Zhao and Daiming Fan, date: 07/05/2017, view: 4870, Q&A: 0
    [Abstract] Tumorigenicity refers to the ability of cultured cells to develop viable tumors in immune-deficient animals. The goal of this protocol is to illustrate tumorigenicity assay by subcutaneous tumor-cell-transplantation in nude mice. Target cells are transplanted to 6-week-old nude mice subcutaneously and the tumor growth is monitored over a period of ...
    Melanoma Stem Cell Sphere Formation Assay
    Authors:  Alessandra Tuccitto, Valeria Beretta, Francesca Rini, Chiara Castelli and Michela Perego, date: 04/20/2017, view: 3300, Q&A: 0
    [Abstract] Self-renewal is the ability of cells to replicate themselves at every cell cycle. Throughout self-renewal in normal tissue homeostasis, stem cell number is maintained constant throughout life. Cancer stem cells (CSCs) share this ability with normal tissue stem cells and the sphere formation assay (SFA) is the gold standard assay to assess stem ...
    Isolation of Primary Breast Cancer Cells from HER2 Transgenic Mice
    Authors:  Shou Liu and Hexin Chen, date: 10/05/2016, view: 4334, Q&A: 0
    [Abstract] HER2 is a tyrosine kinase receptor, which is overexpressed in about 30% of breast cancer patients. Its overexpression leads to mammary tumorigenesis and increased invasion and metastasis (Slamon et al., 1987). HER2 transgenic mouse (FVB/N-MMTVneu mouse) is a well-established model of mammary tumor in human (Fantozzi and Christofori, ...
    In vitro and in vivo Limiting Dilution Assay for Colorectal Cancer
    Authors:  Lauren Agro and Catherine A O’Brien, date: 11/20/2015, view: 9895, Q&A: 0
    [Abstract] The in vitro limiting dilution assay is used to determine the colorectal cancer initiating cell (CC-IC) frequency of a CC-IC enriched suspension culture, grown in growth factor enriched serum free media. The in vivo limiting dilution assay is used to determine the colorectal cancer initiating cell frequency of a primary ...
