    Sebinger Culture: A System Optimized for Morphological Maturation and Imaging of Cultured Mouse Metanephric Primordia
    Authors:  Mona Elhendawi and Jamie A. Davies, date: 02/20/2018, view: 6, Q&A: 0
    Here, we present a detailed protocol on setting up embryonic renal organ cultures using a culture method that we have optimised for anatomical maturation and imaging. Our culture method places kidney rudiments on glass in a thin film of medium, ...
    Sebinger Culture: A System Optimized for Morphological Maturation and Imaging of Cultured Mouse Metanephric Primordia
    Authors:  Mona Elhendawi and Jamie A. Davies, date: 02/20/2018, view: 6, Q&A: 0
    [Abstract] Here, we present a detailed protocol on setting up embryonic renal organ cultures using a culture method that we have optimised for anatomical maturation and imaging. Our culture method places kidney rudiments on glass in a thin film of medium, which results in very flat cultures with all tubules in the same image plane. For reasons not yet ...
    How to Catch a Smurf? – Ageing and Beyond…
    In vivo Assessment of Intestinal Permeability in Multiple Model Organisms
    [Abstract] The Smurf Assay (SA) was initially developed in the model organism Drosophila melanogaster where a dramatic increase of intestinal permeability has been shown to occur during aging (Rera et al., 2011). We have since validated the protocol in multiple other model organisms (Dambroise et al., 2016) and have utilized the ...
    Preparation of Precisely Oriented Cryosections of Undistorted Drosophila Wing Imaginal Discs for High Resolution Confocal Imaging
    Authors:  Samuel Petshow and Marcel Wehrli, date: 02/05/2018, view: 141, Q&A: 0
    [Abstract] The combination of immunofluorescence and laser scanning confocal microscopy (LSM) is essential to high-resolution detection of molecular distribution in biological specimens. A frequent limitation is the need to image deep inside a tissue or in a specific plane, which may be inaccessible due to tissue size or shape. Recreating high-resolution 3D ...
    Ex vivo Trophoblast-specific Genetic Manipulation Using Lentiviral Delivery
    Authors:  Damayanti Chakraborty, Masanaga Muto and Michael J. Soares, date: 12/20/2017, view: 400, Q&A: 0
    [Abstract] In this protocol report, we describe a lentiviral gene delivery technique for genetic modification of the rat trophoblast cell lineage. Lentiviral packaged gene constructs can be efficiently and specifically delivered to the trophoblast cell lineage of the blastocyst. The consequences of ‘gain-of-function’ and ‘loss-of-function’ blastocyst ...
    Biochemical Isolation of Myonuclei from Mouse Skeletal Muscle Tissue
    Authors:  Alicia A Cutler, Anita H Corbett and Grace K Pavlath, date: 12/20/2017, view: 618, Q&A: 0
    [Abstract] Skeletal muscle provides the contractile force necessary for movement, swallowing, and breathing and, consequently, is necessary for survival. Skeletal muscle cells are unique in that they are extremely large cells containing thousands of nuclei. These nuclei must all work in concert to maintain skeletal muscle function and thereby maintain life. ...
    Notch Ligand Binding Assay Using Flow Cytometry
    Authors:  Shweta Varshney and Pamela Stanley, date: 12/05/2017, view: 736, Q&A: 0
    [Abstract] Notch signaling is an evolutionarily conserved signaling pathway that plays an indispensable role during development, and in the maintenance of homeostatic processes, in a wide variety of tissues (Kopan, 2012; Hori et al., 2013). The multifaceted roles of Notch signaling are stringently regulated at different levels. One of the most ...
    Mandibular Explant Assay for Investigating Extrinsic Stimuli on Bone and Cartilage Development
    Authors:  Jamie Jiang, Jessica W. Bertol and Walid D. Fakhouri, date: 12/05/2017, view: 557, Q&A: 0
    [Abstract] A major issue in developmental biology is to determine how embryonic tissues respond to molecular signals in a timely manner and given the position-restricted instructions during morphogenesis, of which Meckel’s cartilage is a classical example. The ex-vivo explant model is a practical and convenient system that allows investigation of ...
    Rapid IFM Dissection for Visualizing Fluorescently Tagged Sarcomeric Proteins
    Authors:  Yu Shu Xiao, Frieder Schöck and Nicanor González-Morales, date: 11/20/2017, view: 709, Q&A: 0
    [Abstract] Sarcomeres, the smallest contractile unit of muscles, are arguably the most impressive actomyosin structure. Yet a complete understanding of sarcomere formation and maintenance is missing. The Drosophila indirect flight muscle (IFM) has proven to be a very valuable model to study sarcomeres. Here, we present a protocol for the rapid ...
    Protocol for Notch-ligand Binding Assays Using Dynabeads
    Authors:  Shogo Sawaguchi, Mitsutaka Ogawa and Tetsuya Okajima, date: 10/20/2017, view: 1123, Q&A: 0
    [Abstract] This protocol describes how to measure interaction between Notch receptors and their ligands by cell-based assay using Dynabeads. We have used the protocol to determine binding capacity between Notch1-transfected HEK293T cells and ligand-coated Dynabeads. Expression of Eogt in Notch1-expressing cells promoted binding toward DLL4-coated ...
    In vitro Co-culture of Mesenchymal Stem Cells and Endothelial Colony Forming Cells
    Authors:  Abbas Shafiee and Kiarash Khosrotehrani, date: 10/20/2017, view: 1318, Q&A: 0
    [Abstract] The discovery of endothelial colony forming cells (ECFCs) with robust self-renewal and de novo vessel formation potentials suggests that ECFCs can be an excellent cell source for cardiovascular diseases treatment through improving neovascularization in the ischemic tissues. However, their engraftment after transplantation resulted to be low. ...
