Fig. 2From: Dystrophin restoration therapy improves both the reduced excitability and the force drop induced by lengthening contractions in dystrophic mdx skeletal muscleNeuromuscular transmission and neuromuscular junction morphology following lengthening contractions in the TA muscle from mdx mice. a Compound muscle action potential (CMAP) (amplitude) in response to 3 Hz nerve stimulation. b CMAP (amplitude) in response to 10 Hz nerve stimulation. c–f representative images of neuromuscular junction morphology using α-bungarotoxin staining. Bar = 20 μm. CMAP compound muscle action potential, Mdx + 9LC after nine lengthening contractions, Mdx LC lengthening contractions in mdx mice, Mdx and C57 before lengthening contractions. n = 6–13 per group for a and b Back to article page
