Abstract
Primary myoblast culture is a valuable tool in research of muscle disease, pathophysiology, and pharmacology. This protocol describes techniques for dissociation of cells from human skeletal muscle biopsies and enrichment for a highly myogenic population by fluorescence-activated cell sorting (FACS). We also describe methods for assessing myogenicity and population expansion for subsequent in vitro study.
Keywords: Skeletal muscle (骨骼肌)Background
Primary human myoblasts from muscle biopsies are a valuable resource for modeling human muscle disease in vitro. Alterations in myoblast proliferation, differentiation, and fusion are features shared by many neuromuscular disorders, and can be used to assay cell-based and pharmacological therapies. Human skeletal muscle biopsies, especially those affected by disease, often contain extensive populations of non-myogenic cells such as adipocytes and fibroblasts. Thus, it is important to purify a myogenic population for in vitro study of skeletal muscle development and disease. Early studies of muscle disease involved use of tissue explants or unpurified dissociated cells (Geiger and Garvin, 1957; Herrmann et al., 1960; Goyle et al., 1967; Bishop et al., 1971), and later, Blau and Webster introduced a pre-plating technique to remove fibroblasts (Blau and Webster, 1981). Here, we describe an effective technique for dissociation of mononuclear cells from human muscle biopsies, and purification of a highly myogenic population utilizing FACS with the cell surface markers CD56 and CD82 (see Note 1). We recently demonstrated that CD82 is an excellent myogenic marker in both human fetal and adult skeletal muscle that is also retained on activated and differentiating myogenic progenitors (Alexander et al., 2016). This protocol also describes methods to culture these myoblasts and confirm a myogenic population by in vitro fusion assay. Isolation and expansion of these cells from normal individuals and from individuals with muscle disorders will help accelerate the development of therapies for human disorders such as muscular dystrophies.
