    Low-viscosity Matrix Suspension Culture for Human Colorectal Epithelial Organoids and Tumoroids
    [Abstract]

    Three-dimensional culture of human normal colorectal epithelium and cancer tissue as organoids and tumoroids has transformed the study of diseases of the large intestine. A widely used strategy for generating patient-derived colorectal organoids and tumoroids involves embedding cells in domes of extracellular matrix (ECM). Despite its success,

    Small Molecule Screening of Primary Human Acute Myeloid Leukemia Using Co-culture and Multiplexed FACS Analysis
    Authors:  Aurelie Baudet, Simon Hultmark, Fredrik Ek and Mattias Magnusson, date: 03/20/2022, view: 549, Q&A: 0
    [Abstract]

    Ex vivo culture of primary acute myeloid leukemia (AML) cells is notoriously difficult due to spontaneous differentiation and cell death, which hinders mechanistic and translational studies. To overcome this bottleneck, we have implemented a co-culture system, where the OP9-M2 stromal cells support the growth, but most notably limit the

    Reconstruction of Human AML Using Functionally and Immunophenotypically Defined Human Haematopoietic Stem and Progenitor Cells as Targeted Populations
    Authors:  Bernd B. Zeisig, Tsz Kan Fung, Estelle Troadec and Chi Wai Eric So, date: 12/20/2021, view: 1788, Q&A: 0
    [Abstract]

    Acute myeloid leukaemia (AML) is a highly heterogenous blood cancer, in which the expansion of aberrant myeloid blood cells interferes with the generation and function of normal blood cells. Although key driver mutations and their associated inhibitors have been identified in the last decade, they have not been fully translated into better

    Strategy of Isolating ‘Primed’ Tumor Initiating Cells Based on Mitochondrial Transmembrane Potential
    Authors:  Brian Spurlock, Vidya Sagar Hanumanthu and Kasturi Mitra, date: 03/05/2021, view: 3411, Q&A: 0
    [Abstract]

    Various stem cells have been found to be dependent on mitochondrial energetics. The role of mitochondria in regulating the self-renewal of normal stem cells and stem-like tumor initiating cells (TICs) is increasingly being appreciated. We proposed that TIC populations have a sub population of cells that are “primed” by mitochondria for

    Modeling NOTCH1 driven T-cell Acute Lymphoblastic Leukemia in Mice
    Authors:  Agnieszka A. Wendorff and Adolfo A. Ferrando, date: 05/20/2020, view: 3661, Q&A: 0
    [Abstract] T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy that arises from transformation of T-cell primed hematopoietic progenitors. Although T-ALL is a heterogenous and molecularly complex disease, more than 65% of T-ALL patients carry activating mutations in the NOTCH1 gene. The majority of T-ALL–associated ...
    Isolation of Stem Cells, Endothelial Cells and Pericytes from Human Infantile Hemangioma
    Authors:  Lan Huang and Joyce Bischoff, date: 01/20/2020, view: 2818, Q&A: 0
    [Abstract] Infantile hemangioma (IH) is a vascular tumor noted for its excessive blood vessel formation during infancy, glucose-transporter-1 (GLUT1)-positive staining of the blood vessels, and its slow spontaneous involution over several years in early childhood. For most children, IH poses no serious threat because it will eventually involute, but a subset ...
    Investigating Neural Stem Cell and Glioma Stem Cell Self-renewal Potential Using Extreme Limiting Dilution Analysis (ELDA)
    Authors:  Hong PT Nguyen, Paul M Daniel, Gulay Filiz and Theo Mantamadiotis, date: 09/05/2018, view: 7501, Q&A: 0
    [Abstract] Glioma stem cells (GSC) grown as neurospheres exhibit similar characteristics to neural stem cells (NSC) grown as neurospheres, including the ability to self-renew and differentiate. GSCs are thought to play a role in cancer initiation and progression. Self-renewal potential of GSCs is thought to reflect many characteristics associated with ...
    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: 8305, 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: 5795, 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: 11071, 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 ...
