Figure Lengend Snippet: Immunohistochemical analyses of MHCI and MHCII expression in PNAs. (A, B) Fluorescent images of nerve cross-sections immunostained for MHCI (top row, green) and MHCII (bottom row, green) at 14 and 21 days PO, respectively. Nuclei are stained with 4′,6-diamidino-2-phenylindole (DAPI) (blue). Scale bar: 50 µm. (C) Quantification of MHCI staining area. Two-way ANOVA, (α) F (4, 36) = 1.65, ns, (β) F (2, 36) = 1.23, ns, (γ) F (2, 36) = 4.96, P = 0.0125. (D) Quantification of MHCII staining area. Two-way ANOVA, (α) F (4, 36) = 0.74, ns, (β) F (2, 36) = 3.38, P = 0.0451, (γ) F (2, 36) = 8.69, P = 0.0008. Tukey’s post hoc test was used. * P < 0.05. ANOVA: Analysis of variance; LS: loose-sutured; NC: negative control; ns: not significant; PEG: polyethylene glycol fusion; PNAs: peripheral nerve allografts; PO: postoperatively; Unop: Unoperated.
