The treatment effects of different hydrogels on SCI mice. a Scheme of the surgical process of hemisected spinal cord repair with hydrogel. b Images of implanting hydrogels during SCI operation. (i) The spinal cord was exposed intra-operatively. (ii) A nanocomposite hydrogel was implanted in SCI intra-operatively. (iii) The spinal cord specimen was obtained at 6 weeks after surgery. c BBB scores of mice at 6 weeks after surgery. n = 6 animals in each group. Error bars represent SD. *p < 0.05; **p < 0.01. All groups were compared with the SCI group. d Representational footprints of Sham, SCI, GO/PVA, MoS2/PVA, and MoS2/GO/PVA groups. The mouse front paw footprints were black, and the hind paw footprints were red. e Representative H&E images of spinal cords of Sham, SCI, GO/PVA, MoS2/PVA, and MoS2/GO/PVA groups at 6 weeks postoperation, Scale bar = 50 μm
