    Lipid Mixing Assay for Murine Myoblast Fusion and Other Slow Cell-cell Fusion Processes
    [Abstract] Lipid mixing (redistribution of lipid probes between fusing membranes) has been widely used to study early stages of relatively fast viral and intracellular fusion processes that take seconds to minutes. Lipid mixing assays are especially important for identification of hemifusion intermediates operationally defined as lipid mixing without content ...
    RNA Sequencing of Single Myofibers from Mus musculus
    Authors:  Darren M. Blackburn, Felicia Lazure and Vahab D. Soleimani, date: 02/20/2020, view: 2134, Q&A: 0
    [Abstract] Whole transcriptome analysis is a key method in biology that allows researchers to determine the effect a condition has on gene regulation. One difficulty in RNA sequencing of muscle is that traditional methods are performed on the whole muscle, but this captures non-myogenic cells that are part of the muscle. In order to analyze only the ...
    Immunohistochemical Identification of Muscle Fiber Types in Mice Tibialis Anterior Sections
    Authors:  Vanitha V. Rao and Abhishek Mohanty, date: 10/20/2019, view: 1909, Q&A: 0
    [Abstract] Mammalian skeletal muscle is a metabolically active tissue that is made up of different types of muscle fibers. These myofibers are made up of important contractile proteins that provide force during contraction of the muscle like actin and myosin. Murine myofibers have been classified into 4 types: Type I, Type IIa, Type IIb and Type IIX. Each ...
    Muscle Function Assessment Using a Drosophila Larvae Crawling Assay
    Authors:  Yanina Post and Achim Paululat, date: 07/20/2018, view: 3531, Q&A: 0
    [Abstract] Here we describe a simple method to measure larval muscle contraction and locomotion behavior. The method enables the user to acquire data, without the necessity of using expensive equipment (Rotstein et al., 2018). To measure contraction and locomotion behaviour, single larvae are positioned at the center of a humidified Petri dish. ...
    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: 7284, 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. ...
    Isolation of Mouse Cardiac Neural Crest Cells and Their Differentiation into Smooth Muscle Cells
    Authors:  Xia Wang and Sophie Astrof, date: 09/05/2017, view: 5781, Q&A: 0
    [Abstract] Cardiac neural crest cells (CNCCs) originate at the dorsal edge of the neural tube between the otic pit and the caudal edge of the 3rd somite, and migrate into the pharyngeal arches and the heart. We have shown that fibronectin (Fn1) plays an important role in the development of the CNCC by regulating the differentiation of CNCCs into ...
    Isolation, Culture, and Staining of Single Myofibers
    Authors:  Yann Simon Gallot, Sajedah M. Hindi, Aman K. Mann and Ashok Kumar, date: 10/05/2016, view: 9922, Q&A: 1
    [Abstract] Adult skeletal muscle regeneration is orchestrated by a specialized population of adult stem cells called satellite cells, which are localized between the basal lamina and the plasma membrane of myofibers. The process of satellite cell-activation, proliferation, and subsequent differentiation that occurs during muscle regeneration can be ...
