Myotube formation was accompanied by the observation of lateral striations indicative of sarcomeric structures. a Myotubes at 4d, 5d, 9d (DM1) and 42d (DM1) of differentiation were immunostained for the presence of sarcomeric α-actin (Sigma A2172, 1:500 dilution). b Sarcomeric lateral striations were visible in H&E stained myotubes differentiated for 5d, derived from P3 and P5 longissimus dorsi myoblasts.
