    Cell Microencapsulation and Cryopreservation with Low Molecular Weight Hyaluronan and Dimethyl Sulfoxide
    Authors:  H. Gurruchaga, L. Saenz del Burgo, G. Orive, R. M. Hernandez, J. Ciriza and J. L. Pedraz, date: 02/20/2019, view: 668, Q&A: 0
    [Abstract] Cryopreservation is commonly used for the storage of cells, tissues, organs or 3D cell-based products using ultra-low temperatures, which involves the immersion in liquid nitrogen for their long-term preservation. The cryopreservation of several microencapsulated cells is usually performed by the slow freezing with the dimethyl sulfoxide (DMSO) as ...
    Murine Pharmacokinetic Studies
    [Abstract] Murine pharmacokinetics (PK) represents the absorption, distribution, metabolism, and elimination of drugs from the body, which helps to guide clinical studies, ultimately resulting in more effective drug treatment. The purpose of this protocol is to describe a serial bleeding protocol, obtaining blood samples at six time points from single mouse ...
    Using Stable Isotopes in Bone Marrow Derived Macrophage to Analyze Metabolism
    [Abstract] Using gas chromatography mass spectrometry (GC-MS) to analyze the citric acid cycle (CAC) and related intermediates (such as glutamate, glutamine, GABA, and aspartate) is an analytical approach to identify unexpected correlations between apparently related and unrelated pathways of energy metabolism. Intermediates can be as expressed as their ...
    In vivo and in vitro 31P-NMR Study of the Phosphate Transport and Polyphosphate Metabolism in Hebeloma cylindrosporum in Response to Plant Roots Signals
    [Abstract] We used in vivo and in vitro phosphorus-31 nuclear magnetic resonance (31P-NMR) spectroscopy to follow the change in transport, compartmentation and metabolism of phosphate in the ectomycorrhizal fungus Hebeloma cylindrosporum in response to root signals originating from host (Pinus pinaster) or ...
    Preparation of Lipid-Stripped Serum for the Study of Lipid Metabolism in Cell Culture
    Authors:  Aaron M. Hosios, Zhaoqi Li, Evan C. Lien and Matthew G. Vander Heiden, date: 06/05/2018, view: 3014, Q&A: 0
    [Abstract] Studying lipid metabolism in cultured cells is complicated by the fact that cells are typically cultured in the presence of animal serum, which contains a wide, variable, and undefined variety of lipid species. Lipid metabolism can impact cell physiology, signaling, and proliferation, and the ability to culture cells in the absence of exogenous ...
    Measurement of Oxygen Consumption Rate (OCR) and Extracellular Acidification Rate (ECAR) in Culture Cells for Assessment of the Energy Metabolism
    Authors:  Birte Plitzko and Sandra Loesgen, date: 05/20/2018, view: 15925, Q&A: 0
    [Abstract] Mammalian cells generate ATP by mitochondrial (oxidative phosphorylation) and non-mitochondrial (glycolysis) metabolism. Cancer cells are known to reprogram their metabolism using different strategies to meet energetic and anabolic needs (Koppenol et al., 2011; Zheng, 2012). Additionally, each cancer tissue has its own individual ...
    Measurement of ROS in Caenorhabditis elegans Using a Reduced Form of Fluorescein
    Authors:  Shaarika Sarasija and Kenneth R. Norman, date: 04/05/2018, view: 2179, Q&A: 0
    [Abstract] Oxidative stress is implicated in the pathogenesis of various neurodegenerative diseases, including Alzheimer’s disease. Oxidative stress is a result of a disruption of the equilibrium between antioxidants and oxidants, in favor of oxidants. Since mitochondria are major sites of production and reduction of reactive oxygen species (ROS), ...
    Flow Cytometric Quantification of Fatty Acid Uptake by Mycobacterium tuberculosis in Macrophages
    Authors:  Evgeniya V. Nazarova, Maria Podinovskaia, David G. Russell and Brian C. VanderVen, date: 02/20/2018, view: 3095, Q&A: 0
    [Abstract] Mycobacterium tuberculosis (Mtb) has evolved to assimilate fatty acids from its host. However, until recently, there was no reliable way to quantify fatty acid uptake by the bacteria during host cell infection. Here we describe a new method to quantify fatty acid uptake by intracellular bacilli. We infect macrophages with Mtb ...
    Ex vivo Analysis of Lipolysis in Human Subcutaneous Adipose Tissue Explants
    Authors:  Pauline Decaunes, Anne Bouloumié, Mikael Ryden and Jean Galitzky, date: 02/05/2018, view: 2382, Q&A: 0
    [Abstract] Most studies of human adipose tissue (AT) metabolism and functionality have been performed in vitro on isolated mature adipocyte or in situ using the microdialysis technique (Lafontan, 2012). However, these approaches have several limitations. The use of mature isolated adipocytes is limiting as adipocytes are not in their ...
    GC/MS-based Analysis of Volatile Metabolic Profile Along in vitro Differentiation of Human Induced Pluripotent Stem Cells
    [Abstract] Human induced pluripotent stem cells (hiPSCs) are a promising tool in cell-based therapies for degenerative diseases. A safe application of hiPSCs in vivo, requires the detection of the presence of residual undifferentiated pluripotent cells that can potentially cause the insurgence of teratomas. Several studies point out that metabolic ...
