    In vitro Osteoclastogenesis Assays Using Primary Mouse Bone Marrow Cells
    Authors:  Xueqian Zhuang and Guohong Hu, date: 06/05/2018, view: 144, Q&A: 1
    Osteoclasts are a group of bone-absorbing cells to degenerate bone matrix and play pivotal roles in bone growth and homeostasis. The unbalanced induction of osteoclast differentiation (osteoclastogenesis) in pathological conditions, such as ...

    Authors:  Aaron M. Hosios, Zhaoqi Li, Evan C. Lien and Matthew G. Vander Heiden, date: 06/05/2018, view: 307, Q&A: 0
    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 ...

    Authors:  Jan Strnadel, Sang Myung Woo, Sunkyu Choi, Huawei Wang, Marian Grendar and Ken Fujimura, date: 06/05/2018, view: 155, Q&A: 0
    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 ...
    Hyaluronan Isolation from Mouse Mammary Gland
    Authors:  Cornelia Tolg, Mary Cowman and Eva A. Turley, date: 06/05/2018, view: 146, Q&A: 0
    The glycosaminoglycan hyaluronan (HA) is a key component of the extracellular matrix. The molecular weight of HA is heterogeneous and can reach from several million to several hundred daltons. The effect of HA on cell behavior is size dependent; ...
    Intracellular and Mitochondrial Reactive Oxygen Species Measurement in Primary Cultured Neurons
    Reactive oxygen species (ROS) are chemically reactive oxygen containing molecules. ROS consist of radical oxygen species including superoxide anion (O2•−) and hydroxyl radical (•OH) and non-radical oxygen species such as ...
    Expansion of Airway Basal Cells and Generation of Polarized Epithelium
    Authors:  Hannah Levardon, Lael M. Yonker, Bryan P. Hurley and Hongmei Mou, date: 06/05/2018, view: 134, Q&A: 0
    Airway basal stem cells are the progenitor cells within the airway that exhibit the capacity to self-renew and give rise to multiple types of differentiated airway epithelial cells. This stem cell-derived epithelium displays organized architecture ...
    Slow and Fast Desiccation of Single-cell Thick Fronds of Filmy Ferns
    Author:  Marcelo Garcés, date: 06/05/2018, view: 114, Q&A: 0
    Filmy ferns can desiccate and recover after rehydration to resume photosynthesis. Slow and fast desiccation rates were compared in filmy fern fronds to determine whether structural or physiological differences may occur between desiccation rates. ...
    In vitro Osteoclastogenesis Assays Using Primary Mouse Bone Marrow Cells
    Authors:  Xueqian Zhuang and Guohong Hu, date: 06/05/2018, view: 144, Q&A: 1
    [Abstract] Osteoclasts are a group of bone-absorbing cells to degenerate bone matrix and play pivotal roles in bone growth and homeostasis. The unbalanced induction of osteoclast differentiation (osteoclastogenesis) in pathological conditions, such as osteoporosis, arthritis and skeleton metastasis of cancer, causes great pain, bone fracture, hypercalcemia ...
    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: 307, 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 ...
    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: 155, 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 ...
    Hyaluronan Isolation from Mouse Mammary Gland
    Authors:  Cornelia Tolg, Mary Cowman and Eva A. Turley, date: 06/05/2018, view: 146, Q&A: 0
    [Abstract] The glycosaminoglycan hyaluronan (HA) is a key component of the extracellular matrix. The molecular weight of HA is heterogeneous and can reach from several million to several hundred daltons. The effect of HA on cell behavior is size dependent; fragmented HA acts as a danger signal, stimulates cell migration and proliferation and is ...
    Intracellular and Mitochondrial Reactive Oxygen Species Measurement in Primary Cultured Neurons
    [Abstract] Reactive oxygen species (ROS) are chemically reactive oxygen containing molecules. ROS consist of radical oxygen species including superoxide anion (O2•−) and hydroxyl radical (•OH) and non-radical oxygen species such as hydrogen peroxide (H2O2), singlet oxygen (O2). ROS are generated by ...

    Authors:  Hannah Levardon, Lael M. Yonker, Bryan P. Hurley and Hongmei Mou, date: 06/05/2018, view: 134, Q&A: 0
    [Abstract] Airway basal stem cells are the progenitor cells within the airway that exhibit the capacity to self-renew and give rise to multiple types of differentiated airway epithelial cells. This stem cell-derived epithelium displays organized architecture with functional attributes of the airway mucosa. A protocol has been developed to culture and expand ...
    Slow and Fast Desiccation of Single-cell Thick Fronds of Filmy Ferns
    Author:  Marcelo Garcés, date: 06/05/2018, view: 114, Q&A: 0
    [Abstract] Filmy ferns can desiccate and recover after rehydration to resume photosynthesis. Slow and fast desiccation rates were compared in filmy fern fronds to determine whether structural or physiological differences may occur between desiccation rates. Slow desiccation is considered to be more similar to natural conditions experienced by plants that ...
    High Dimensional Functionomic Analysis of Human Hematopoietic Stem and Progenitor Cells at a Single Cell Level
    Authors:  Thomas Luh, Kimberly Lucero, Wenji Ma, Jaeyop Lee, Yu Jerry Zhou, Yufeng Shen and Kang Liu, date: 05/20/2018, view: 404, Q&A: 0
    [Abstract] The ability to conduct investigation of cellular transcription, signaling, and function at the single-cell level has opened opportunities to examine heterogeneous populations at unprecedented resolutions. Although methods have been developed to evaluate high-dimensional transcriptomic and proteomic data (relating to cellular mRNA and protein), ...

    Authors:  Weihuan Wang, Gurnoor Majhail, Cui Lui and Lan Zhou, date: 05/20/2018, view: 211, Q&A: 0
    [Abstract] Osteoblasts are bone marrow endosteum-lining niche cells playing important roles in the regulation of hematopoietic stem cells by secreting factors and cell adhesion molecules. Characterization of primary osteoblasts has been achieved through culture of outgrowth of collagenase treated bone. Immunophenotyping and flow-based analysis of long bone ...
    Virucidal and Neutralizing Activity Tests for Antiviral Substances and Antibodies
    Authors:  Chie Aoki-Utsubo, Ming Chen and Hak Hotta, date: 05/20/2018, view: 256, Q&A: 0
    [Abstract] In a narrow definition, virucidal activity represents the activity by which to interact with and physically disrupt viral particles. In a broad definition, it includes the activity by which to functionally inhibit (neutralize) viral infectivity without apparent morphological alterations of the viral particles. The viral infectivity can be measured ...
