(A) Schematic representation of SCI repair using PAO to create a biomimetic collagen scaffold with unique physical properties. (B, C) Immunofluorescence staining maps of Tuj-1 + and Map-2 + in the injured sites of the individual treatment groups. Scale bars: 1 mm (left) and 50 μm (right and below). (D) Quantitative analysis of the area of Tuj-1 + and Map-2 + cells at the injury site in the different treatment groups. * P < 0.05, ** P < 0.01, *** P < 0.001.
