Chi/PDA-Ps conduits improve motor functional recovery in PNI rats 12 weeks after surgery.

(A) Representative 3D plantar pressure distribution of affected hind limbs and healthy hind limbs for each group. The spread and the toe stress of the right hind limb were greater in the Chi/PDA-Ps group than in the other groups. (B) Quantitative results of the SFI values (n = 3 for each group). (C) Quantitative results of the gastrocnemius muscle wet weight rate (n = 3 for each group). (D) Cross-sectional area of gastrocnemius muscle fibers 12 weeks after surgery. The cross-sectional area of muscle fibers was greater in the Chi/PDA-Ps group than in the other groups. Scale bars: 50 µm. (E) Quantitative results of the cross-section of the gastrocnemius muscle fiber (n = 8 for each group). All data are represented as the mean ± SEM. *P < 0.05, **P < 0.01, vs. Chi group; #P < 0.05, ##P < 0.01, vs. Chi/PDA group (one-way analysis of variance followed by Tukey’s post hoc test). 3D: Three-dimensional; Chi: Chitin; Chi/PDA: polydopamine-coated chitin conduits; Chi/PDA-Ps: polydopamine-coated chitin conduits loaded with functional peptides; PNI: peripheral nerve injury; SFI: sciatic functional index.
