Determination of myogenesis specific genes. Comparison between 93 genes significantly regulated in early adipogenic differentiation (pink arrows) and 112 in myogenic differentiation (purple arrows) of Mouse Satellite Cells (MSC) revealed 67 genes specifically regulated during myogenesis. Among them, 17 genes varied only in MSC and 14 were regulated similarly in C2C12 cells (bold red characters). They represent the 31 genes of interest in this study. Dotted arrows correspond to genes discarded during the screening.
