    Thrombospondin expression in myofibers stabilizes muscle membranes

    Davy Vanhoutte, Tobias G Schips ... Jeffery D Molkentin
    Thrombospondin proteins regulate vesicular trafficking of integrins and other membrane attachment complex proteins to the plasma membrane of skeletal muscle, which provides greater stability and resistance to muscular dystrophy.

    Stage-specific effects of Notch activation during skeletal myogenesis

    Pengpeng Bi, Feng Yue ... Shihuan Kuang
    While Notch activation dedifferentiates newly differentiated muscle cells; it improves the function of muscle fiber as a niche-supporting cell of muscle stem cells.

    Endothelial cell signature in muscle stem cells validated by VEGFA-FLT1-AKT1 axis promoting survival of muscle stem cell

    Mayank Verma, Yoko Asakura ... Atsushi Asakura
    Bulk and single-cell RNA-seq data demonstrated that muscle stem cells express low levels of canonical endothelial cell markers, including VEGFA receptors, and VEGFA-FLT1 pathway has a drastic effect on muscle stem cell survival through AKT1 in vitro and in vivo.
