Figure 1From: The actions of exogenous leucine on mTOR signalling and amino acid transporters in human myotubesCultured human primary myotubes labelled for myogenin. Primary myoblasts were grown to near confluence and induced to differentiate for 7 days. Myogenin (green) was detected by immunocytochemistry using anti-myogenin antibody followed by anti-mouse Alexa 488 secondary antibody. Scale bar = 30 μm.Back to article page
