LAR peptide promoted recovery of diaphragm function after C2 hemisection SCI. (A) Timeline of experimental design. At 8 weeks post injury, EMG recordings were assessed at 3 sub-regions of both the ipsilateral and contralateral hemidiaphragm (dorsal, medial and ventral sub-regions) from C2 hemisection rats receiving either DMSO-only (B) or LAR peptide (C). (B, C) Representative EMG recordings from ipsilateral hemidiaphragm. Top: raw EMG traces; bottom: integrated signals. Quantification of integrated EMG amplitude 8 weeks after C2 hemisection at ventral (D) medial (E) and dorsal (F) sub-regions, n = 8–10 animals per group. Data represent mean ± SEM, *P < 0.05 vs the respective control.
