MiR-222 overexpression and Rbm24 silencing inhibit myoblast fusion. (a) MSC myoblasts transfected in GM with siGFP, miR-222 or siRbm24 duplex RNAs were maintained in GM for 1 day (GM) or shifted to DM for 1 day (1d) or 2 days (2d). Cells were subjected to immunofluorescence with antibodies specific for skeletal Myosin Heavy Chain (MHC) and nuclei were counterstained with Hoechst dye. Scale bar: 100 μm. (b) Quantitation of fusion and MHC-positive (MHC+) cells in DM at 1d and 2d in at least three independent experiments (averages±S.E.) is shown in the table. The percentage of fusion was calculated as the ratio of nuclei in MHC+ myotubes containing three or more nuclei over total nuclei given as 100% at least 500 nuclei were counted for each plate
