    An Optimized Method to Isolate Human Fibroblasts from Tissue for Ex Vivo Analysis
    [Abstract] Despite their involvement in many physiological and pathological processes, fibroblasts remain a poorly-characterized cell type. Analysis of primary fibroblasts while maintaining their in vivo phenotype is challenging: standard methods for fibroblast isolation require cell culture in vitro, which is known to alter phenotypes. ...
    A Cell Culture Model that Mimics Physiological Tissue Oxygenation Using Oxygen-permeable Membranes
    Authors:  Chloe-Anne Martinez, Peter A. Cistulli and Kristina M. Cook, date: 09/20/2019, view: 4742, Q&A: 0
    [Abstract] Dissolved oxygen and its availability to cells in culture is an overlooked variable which can have significant consequences on experimental research outcomes, including reproducibility. Oxygen sensing pathways play key roles in cell growth and behavior and pericellular oxygen levels should be controlled when establishing in vitro models. ...
    Generation of Tumour-stroma Minispheroids for Drug Efficacy Testing
    Authors:  Mark Watters and Eva Szegezdi, date: 01/05/2017, view: 7886, Q&A: 0
    [Abstract] The three-dimensional organisation of cells in a tissue and their interaction with adjacent cells and extracellular matrix is a key determinant of cellular responses, including how tumour cells respond to stress conditions or therapeutic drugs (Elliott and Yuan, 2011). In vivo, tumour cells are embedded in a stroma formed primarily by ...
    Preparation of Recombinant Galectin-3 for Cancer Studies
    Authors:  Kari Tyler, Sok-Hyong Lee and Erwin G. Van Meir, date: 01/05/2016, view: 8203, Q&A: 0
    [Abstract] Galectin-3 is a member of a class of proteins termed Galectins, characterized by their ability to bind glycans containing β-galactose (Cummings and Liu, 2009). Galectin-3 binds preferentially to proteoglycans terminating with N-acetyllactosamine (LacNAc) chains (i.e., tandem repeats of galactose) (Newlaczyl and Yu, 2011). Galectin-3 is ...
    Three Dimensional Spheroid Co-culture Invasion Assay
    Authors:  Eldo T Verghese and Thomas A Hughes, date: 01/05/2015, view: 11977, Q&A: 0
    [Abstract] The assay was developed to investigate the impact of stromal cells of different types (in our case breast cancer associated fibroblasts stably manipulated to modify expression of genes of interest) on the invasive capacity of epithelial cancer cells (in our case breast cancer cell lines) (Verghese et al., 2013). Typical two dimensional ...
    Three-dimensional Invasion Assay
    Authors:  Wen-Hao Yang and Muh-Hwa Yang, date: 09/05/2013, view: 11351, Q&A: 0
    [Abstract] The invasive ability of cancer cells is a crucial function for cancer metastasis and the surrounding microenvironment of cancer cells in living tissues is three-dimension (3D). Therefore, to establish an in vitro invasion assay in a 3D system to predict cancer invasive ability is valuable in the research for cancer metastasis. Here, we ...
