Cytotoxicity of Chi/PDA-Ps conduits.

(A) Schematic representation of SCs seeded onto Chi/PDA-Ps films. (B) The survival ability of SCs seeded on different films and analyzed with a live/dead staining kit. The number of live cells (green, calcein-AM) was lower in the Chi group than in the other two groups, and the number of dead cells (red, propidium iodide) was greater in the Chi group than in the other two groups. Scale bars: 50 μm. (C) Quantitative results of the percent of dead/live cells. All data are represented as the mean ± SEM (n = 3 for each group). *P < 0.05, **P < 0.01, vs. Chi group (one-way analysis of variance followed by Tukey’s post hoc test). Chi: Chitin; Chi/PDA: polydopamine-coated chitin conduits; Chi/PDA-Ps: polydopamine-coated chitin conduits loaded with functional peptides; SCs: Schwann cells.
