Fusion index of immortalized FSHD myotubes in the presence of berberine. Immortalized FSHD myotubes (A). FSHD-A5 or (C). FSHD-6 were treated with berberine at the second day of differentiation. Myosin heavy chain and nuclei were stained at the fourth day of differentiation with MF20 antibody and DAPI, respectively. Scale bar: 100 μm. Quantifying cell fusion index results for (B) FSHD-A5 and (D) FSHD-6, with nuclei counted in myotubes containing more than two nuclei and expressed as a percentage of the total nuclei present. Independent treatment at each concentration was performed, N = 6, *P < 0.05; **P < 0.01; ***P < 0.001, one -way ANOVA. Error bars represent S.E.M.
