Confocal immunofluorescence reaction of utrophin (green) in control (a), mdx (b), and PDN mdx (c) muscles. Control myofibers show a light membrane utrophin expression (a), while the mdx animals show a faint and discontinuous green fluorescence on the sarcolemmal level, and PDN myofibers display an intense sarcolemmal fluorescence urtophin signal (c). Scale bar: a–c, 25 μm.
