Evaluation of skeletal muscle differentiation for the different samples at D7.

<p>(a) Relative gene expression levels for ten genes important for skeletal muscle differentiation, compared between the different experimental groups (F, F+BNNT+US, μG and μG+BNNT+US). mRNA analyses were run in quadruplicate; (b) confocal fluorescence images of myotubes on the different samples: myosin heavy chain is shown in red, α-actinin is shown in green, nuclei are shown in blue. Scale bar = 100 μm. * = p<0.05, ** = p<0.01.
