Expression of myogenic and early step adipogenic markers. A. The expression of four myogenic regulation factors (MyoG (circles), MyoD1 (squares), Myf5 (diamonds), Myf6 (triangles)) during satellite cell differentiation in myotubes (black) and satellite cell trans-differentiation in early fat storage cells (white); standard error was calculated from three independent experimentations. B. Relative expression of early adipogenic markers Ppara and Dlk1, in myotubes (black) and early fat storage cells (white) in comparison with expression in undifferentiated satellite cells, triplicates were used to calculate the standard error.
